We also requested dossiers of information from pharmaceutical manufacturers erectile dysfunction treatment pdf purchase malegra fxt 140 mg with amex. Review Methods Study selection buy generic erectile dysfunction drugs 140 mg malegra fxt for sale, data abstraction erectile dysfunction incidence age buy discount malegra fxt 140 mg, validity assessment, grading the strength of the evidence (SOE), and data synthesis were all carried out according to standard Drug Effectiveness Review Project methods. Results Most of the evidence was limited to adult populations. Most of the included studies evaluated intermediate outcomes, such as HbA1c or weight. Very few studies reported health outcomes and few studies were longer than 6 months. For the amylin agonists, DPP-IV inhibitors, and GLP-1 agonists, we found no studies that focused on health outcomes as primary outcomes. Some studies of these drug classes reported some health outcomes such as all-cause mortality or number of people with macrovascular disease among secondary outcomes or adverse events, but overall evidence was generally insufficient to determine how medications in these classes compare with other treatments for their impact on health outcomes. For the newer diabetes drugs (pramlintide, sitagliptin, saxagliptin, exenatide, and liraglutide), all of the included medications were efficacious for reducing HbA1c compared with placebo. For reduction in HbA1c, pramlintide was similar to rapid acting insulin analog when added to insulin glargine or detemir (low SOE); sitagliptin monotherapy was less efficacious than metformin or glipizide monotherapy (low SOE); sitagliptin was not significantly different than rosiglitazone when either was added to metformin (moderate SOE); and there was no comparative evidence for saxagliptin (insufficient SOE). One head-to-head trial comparing exenatide with liraglutide reported a slightly greater reduction in HbA1c with liraglutide (between group difference −0. For reduction in HbA1c, exenatide was similar to glibenclamide (low SOE), rosiglitazone (low SOE), and insulin (with both groups also receiving oral diabetes agents, moderate SOE). Liraglutide-treated subjects had greater reductions in HbA1c than subjects treated with glargine (low SOE), rosiglitazone (low SOE), or sitagliptin (low SOE), and similar or greater reductions than those treated with glimepiride (insufficient SOE). For weight, pramlintide, exenatide, and liraglutide (doses of 1. Sitagliptin and saxagliptin are likely weight neutral. Most studies evaluating weight change were 6 months or less and it is uncertain whether weight loss is sustained long-term. Rates of hypoglycemia were lower with sitagliptin than with glipizide (moderate SOE), with liraglutide than exenatide (low SOE), and with liraglutide than glimepiride (high SOE). Hypoglycemia rates were similar to placebo for sitagliptin and saxagliptin (low SOE) and were similar between exenatide and insulin (moderate SOE). Rates of gastrointestinal side effects were higher with exenatide and liraglutide than with comparators. For the TZDs, the available evidence indicates that pioglitazone and rosiglitazone are not statistically significantly different in their ability to reduce HbA1c (moderate SOE). Further, there were no significant differences in ability to reduce HbA1c between either TZD and sulfonylureas or metformin (moderate to high SOE). Both TZDs increase the risk of heart failure (high SOE), edema (high SOE), and fractures in women (moderate SOE). The risk of hypoglycemia is reduced with TZDs when compared with sulfonylureas; the risk is similar to the risk with metformin (high SOE). Both TZDs cause a similar degree of weight gain to that caused by sulfonylureas (moderate SOE). Although rosiglitazone now has restricted access due to an increased risk of cardiovascular adverse events, we found no evidence of increased all-cause mortality or cardiovascular mortality with pioglitazone; some studies suggest reduced risk of all- cause and cardiovascular mortality with pioglitazone (low SOE) For the FDCPs, we found no head to head trials that compared HbA1c control between any 2 FDCPs (insufficient SOE). Therapy with Avandamet, Avandaryl, Actoplus Met, or dual therapy with metformin and sitagliptin produced statistically significantly greater reductions in HbA1c compared to monotherapy with any of their respective components. Conclusion All of the included medications were efficacious for reducing HbA1c and none of the newer medications appear to cause weight gain. Little data was available to evaluate the long-term effectiveness of the newer medications compared with more established treatments, limiting our ability to determine how to best incorporate newer medications into clinical practice. What is the comparative efficacy and effectiveness of newer diabetes medications, TZDs, and drug combinations (administered as fixed dose combination products or dual therapy) for children and adults with diabetes mellitus?

A retrospective analysis of the Boehringer Ingelheim database showed a higher risk for females with CD4 T cell counts >250 cells/µl and for males >400/µl impotence divorce discount malegra fxt 140 mg buy. Although these findings have not been confirmed by other studies (Manfredi 2006 erectile dysfunction and causes cheap 140 mg malegra fxt mastercard, Peters 2010) erectile dysfunction overweight purchase malegra fxt 140 mg free shipping, the Indications and Usage section advises against starting nevirapine treatment above these CD4 T cell counts in treatment-naïve patients unless the benefits clearly outweigh the risks (Mallolas 2006, De Lazarri 2008). In general, nevirapine should be avoided in patients with liver cirrhosis Child–Pugh class B or C (Nunez 2010). Liver toxicity occurs usually early during ART (within 18 weeks of starting) and may progress to liver failure despite laboratory monitoring. Readministration must be discussed carefully and should, whenever possible, be avoided. In patients treated with efavirenz or rilpivirine, minor enzyme elevations are generally safe and usually resolve so that a treatment change may not be necessary (Gutierrez 2008, Kontorinis 2003, Cohen 2011, Molina 2011). Protease inhibitors and INSTIs Atazanavir (as well as indinavir) inhibit the hepatic enzyme UDP glucuronosyl-trans- ferase, inducing non-dangerous hyperbilirubinemia in up to 50% of patients (Torti 2009). UGT1A1*28 variant allele seems to be a predictor of severe hyperbilirubine- mia (Turatti 2012). Atazanavir was safe in end-stage liver disease patients, hepatitis coinfected patients and those with liver fibrosis (Guaraldi 2009, Pineda 2008). While darunavir and atazanavir were not associated with increased liver morbiditiy, other PIs such as tipranavir/r are associated with a higher risk of transaminase elevations (Hicks 2006). In all cases of unknown liver enzyme increase, hepatitis diagnostics (including HAV, HBV, HCV, HEV), syphilis testing (EBV and CMV) and abdominal ultrasound is recommended. In case of a more chronic enzyme elevation other metabolic diseases, such as Wilson disease, hemochromatosis, alpha-1-antitrypsin deficiency, 284 ART autoimmune hepatitis or (non-alcoholic) fatty liver disease must be excluded. In case of acute liver failure or increase in transaminases, more frequent testing is necessary. ART discontinuation may not be necessary, unless acute >5-fold increase of transam- inases. Ultimately a liver biopsy can reveal macro- and microvesicular steatosis and mitochondrial alterations in NRTI-induced steatosis and is therefore helpful to distinguish NRTI-induced hepatopathy from other causes. Moderate liver enzyme elevation has also been reported in several INSTI studies. Dolutegravir, elvitegravir and raltegravir can lead to mild to moderate increase in liver enzymes. Rates of elevated liver enzymes in patients with elvitegravir were comparable to those treated with efavirenz or boosted atazanavir (DeJesus 2012, Sax 2012). Dolutegravir-associated increase in liver enzymes was mostly seen during immune reconstitution and coinfection with viral hepatitis (Curtis, 2014). In any case, transaminase elevation due to INSTI leads only in a very rare number of cases to discontinuation. Renal problems Renal complications are mostly seen with tenofovir disoproxil fumarate (TDF) or less likely with atazanavir (see HIV and Renal Function). Rilpivirine, cobicistat, and dolute- gravir reduce the tubular secretion of creatinine by different mechanisms, inducing a decrease of estimated glomerular filtration rate. Calculated eGFR results might decrease after beginning a new treatment and will establish a plateau quickly (Sax 2012, Curtis 2014). Clinicians should carefully monitor renal function in order to identify possible alterations suggestive of a true renal functional impairment. Additional renal monitoring (urine dipstick, alpha-1- microglobulin, cystatin C-GFR or the albumin/creatinine ratio) should be used for renal safety monitoring or screening of tubular injury. Besides renal problems, rhabdomyolysis is a rare but dangerous event. Rhabdo- myolysis has been reported during abacavir HSR (Fontaine 2005), statin and boosted PI use as a consequence of CYP450 interactions and in rare cases after raltegravir exposure (Dori 2010). Immediate action should be taken if patients complain about muscle pain and/or otherwise unexplained elevated creatine kinase levels, to avoid more severe kidney injury. Tenofovir disoproxil fumarate (TDF) In ART-naïve patients tenofovir is associated with a greater decline in renal function and a higher risk of proximal tubular dysfunction: 4.

Mean age was 61 years old and 26% were female and 92 erectile dysfunction causes young males buy malegra fxt with a mastercard. It compared prasugrel (60 mg load erectile dysfunction meds online malegra fxt 140 mg on line, followed by 10 mg daily) to clopidogrel (300 mg load erectile dysfunction jelqing purchase generic malegra fxt on-line, followed by 75 mg daily). Two other fair-quality head-to-head trials were smaller (n= 201 and n=905) and shorter (14 days and 30 days) studies to establish dose and had too few events to evaluate. Ticlopidine compared with clopidogrel Seven trials compared ticlopidine with clopidogrel in patients who had undergone placement of a 29, 30-34, 35, 37 29, 31 coronary stent. Two included only patients with acute coronary syndrome. Patients enrolled in 3 other fair-quality trials included 50% or fewer patients with acute coronary 30-34 35, 37 syndrome. Patient histories included previous myocardial infarction (36. The mean age was 60 years and predominately male (77%). The primary endpoint consisted of major peripheral bleeding or complications, neutropenia or thrombocytopenia, or early discontinuation of study drug as the result of a noncardiac adverse event during the study-drug treatment period. All-cause mortality was not reported and there was a single cardiovascular death reported in the clopidogrel loading dose group. The relative risk of revascularization of ticlopidine compared with clopidogrel no load was 0. The diagnosis of acute coronary syndrome included patients with acute or rapidly worsening symptoms thought to be due to coronary artery disease as well as non-ST segment elevation myocardial infarction. All patients received aspirin 160 mg daily and GP IIb/IIIa infusion. During the 180 day follow-up, the relative risk of target vessel revascularization for ticlopidine compared to clopidogrel was 0. Three other studies were fair quality and included patients with stable or unstable angina 30-34 or post myocardial infarction as the reason for their stent placement. In a study with 4 weeks Newer antiplatelet agents 23 of 98 Final Update 2 Report Drug Effectiveness Review Project 33 of treatment, followed by 2. Over 28 months (24 months without treatment) the primary endpoint of cardiovascular mortality was significantly lower in patients assigned to receive ticlopidine compared to those taking clopidogrel (relative risk, 0. In addition, all-cause mortality was lower with ticlopidine compared with clopidogrel (relative risk, 0. Because treatment was not continued beyond 4 weeks, it is not clear how these results relate to results from other studies. In an open-label trial in a broad population of 1016 patients with successful implantation of a stent in a native coronary artery or in a coronary artery bypass graft, cardiac death at 30 days occurred more frequently in the ticlopidine group but did not reach statistical significance 34 (relative risk, 2. There was no difference in target vessel revascularization (relative risk, 0. Ticlopidine and clopidogrel were given for only the first 2 weeks of follow-up in this study. Follow-up was only 6 days and there was a nonsignficant increased rate in major clinical events (death, acute myocardial infarction, percutaneous coronary intervention, or bypass surgery) with ticlopidine compared with clopidogrel. Two additional studies were poor quality due to small sample size, lack of reporting the method for randomization, allocation concealment, and masking, or were 35, 37 unmasked. Both studies utilized doses of aspirin that are no longer used in clinical practice. Indirect evidence 38 The active-control study performed by Hall, et al. The primary aim of the study was to assess the antiplatelet effects of these various regimens. In that regard, ticlopidine plus aspirin was superior in terms of platelet aggregation parameters and platelet activation markers compared with aspirin or ticlopidine alone. The study randomization was inadequate, allocation was not concealed nor 40 was the outcome assessor masked, and the study was rated poor quality.

A thor- ough documentation should be kept in case of disagreement from payors impotence low testosterone discount 140 mg malegra fxt visa. Even within drug classes erectile dysfunction drugs best 140 mg malegra fxt purchase amex, there are astonishing differences erectile dysfunction drugs in bangladesh order genuine malegra fxt line. For example, the PI indinavir (Crixivan, hardly used today) is relatively cheap in most countries, while the PI tipranavir (Aptivus) is more than three times the price. Even in recommended first-line therapies in guidelines there are great price variations: PIs are almost double the price of NNRTIs in many countries. A salvage therapy for a patient with multiresistant virus can amount to as much as € 30,000–50,000 and more per year. For pricing in low- or middle-income countries, please refer to the chapter Global Access to HIV Treatment. It is difficult to comprehend the pricing policies of pharmaceutical companies. The reason why prices for directly competing agents (3TC and FTC) are almost exactly the same, whilst prices for other agents of the same drug class differ by 200–300%, cannot be explained by development costs alone. There is no doubt that ART is a money-maker and the market is full of competitors – monopolies and patents are being protected. Despite all the criticism and price discussions, two facts cannot be forgotten: First, the high development costs for new medicines can rise to a billion dollars or more. Even a licensed drug such as T-20 may never recoup its development costs. According to Roche, research and development alone chewed up 600 million dollars. To cover such production costs, thousands of patients worldwide would have to be treated with T-20 for several years – a very unrealistic scenario. Overview of antiretroviral agents 71 Second, there is hardly a more effective therapy than antiretroviral therapy. US estimations assume an expenditure of between $13,000 and $23,000 per additional QALY (quality-adjusted life year) (Freedberg 2001). Compared to many other thera- pies this is relatively cheap. ART reduces the cost of expensive treatment of oppor- tunistic infections, inpatient and outpatient care. In one German study, between 1997 and 2001 total annual spending per patient decreased from € 35,865 to € 24,482 (Stoll 2002). Many patients return to work, resulting in an overall economic gain for society (Sendi 1999). Therefore, it should be expected from patients to use up remaining packets of drugs, etc. Concerns of pill reduction or doubts about long-term toxicity should be part of an ongoing discussion with patients. All patients need to be made aware of the costs of medication so they can better understand the value of the therapy. This way, mountains of unused pills will not be wasted if signs of intolerability or complicated adverse events occur. If response to ART is positive and its effects constant, prescriptions can then be done for a maximum period of three months. Many companies now offer three-month supply packages. Nucleoside Analogs (NRTIs) Mechanism of action Nucleoside analogs (“nukes”) are also referred to as nucleoside reverse transcriptase inhibitors (NRTIs). Their target is the HIV enzyme reverse transcriptase. Acting as alternative substrates, they compete with physiological nucleosides, differing from them only by a minor modification in the ribose molecule.

Therefore erectile dysfunction klonopin 140 mg malegra fxt purchase with mastercard, no firm conclusions can be drawn about the comparative efficacy of these drugs erectile dysfunction pills from china malegra fxt 140 mg buy online. In addition diabetes and erectile dysfunction causes order 140 mg malegra fxt amex, it should be noted that only one study compared medications from the same groups (i. The other two studies compared medications from different groups i. In clinical practice, these medications are often used together since they work in different ways to improve bowel movements. For comparative safety in adults 43 we found four head-to-head trials comparing PEG 3350 with lactulose, lactulose with psyllium (2 65, 66 45 trials), and PEG 3350 with psyllium. All four of these studies had severe methodological limitations and were rated as poor quality for assessment of adverse events and no firm conclusions can be drawn about the comparative safety of these drugs. For pediatric populations, the evidence for general efficacy and safety is very poor quality and sparse. We found no studies on the general efficacy, tolerability, or safety of docusate calcium, docusate sodium, lactulose, lubiprostone, and psyllium that met our eligibility criteria. All of the studies we found were rated poor quality and results should be interpreted with caution. For comparative evidence of general efficacy and safety in pediatric populations, we found just one head- 46 to-head trial comparing PEG 3350 with lactulose. However, this study was of poor quality due to methodological limitations. The results should be interpreted cautiously due to the poor quality of the evidence. Constipation Drugs Page 69 of 141 Final Report Drug Effectiveness Review Project Likewise, no evidence is available to determine the ideal treatment duration of drugs used to treat chronic constipation or when treatments should be switched if patients do not respond. Similarly, we did not find any studies published as full text articles specifically designed to compare the effect of constipation drugs in particular subpopulations. The lack of scientific evidence for drugs used to treat constipation has been pointed out in several 71, 73-75 systematic reviews. Some of these studies focused on interventions not included in this report; others examined the efficacy and safety in populations with occasional constipation. All of them stress the lack of high quality evidence to support the efficacy and safety of most interventions. Nevertheless, the absence of evidence of an effect cannot be interpreted as evidence of no effect. Therefore, it is important that well conducted future studies reliably establish the efficacy of all commonly used medications used for treatment of constipation. Furthermore, the comparative efficacy and effectiveness of first-line over-the-counter treatments and first-line prescription treatments have to be compared. Moreover, it is important to examine whether new second-line treatments, such as lubiprostone, have an additional, clinically significant treatment benefit as well as better tolerability and safety compared with other available interventions. In addition, it is important that these studies will investigate the effects of these interventions on a variety of constipation related symptoms including straining, bloating, and abdominal discomfort as well as on the patients’ overall well-being and quality of life. Finally, future research should more fully assess comprehensive safety and tolerability data, because much of the current literature does not adequately address these issues. This data will provide clinicians with helpful information needed for better selection of appropriate intervention for patients with chronic functional constipation.

Only high-dose antiemetics had headache rates higher than placebo best erectile dysfunction pills treatment discount malegra fxt 140 mg fast delivery, but the difference was not statistically significant at any dose level reflexology erectile dysfunction treatment order malegra fxt with a mastercard. Antiemetics Page 39 of 136 Final Report Update 1 Drug Effectiveness Review Project Safety Rare occurrences of QTc prolongation are reported in the product labels of with dolasetron erectile dysfunction doctors in queens ny purchase malegra fxt 140 mg amex, ondansetron, and palonosetron. However, we found only 1 single-blind study that prospectively measured QTc changes associated with treatment of postoperative nausea and vomiting by 191 intravenous droperidol 0. Patients in this study were 85 consecutive adults who experienced postoperative nausea and vomiting in the recovery room and who were assigned to treatment with droperidol or ondansetron based on the judgment of the attending anesthesiologist. Electrocardiograms were obtained immediately before administration of antiemetic drug and multiple times between 1 and 15 minutes after administration. Electrocardiograms were evaluated by a clinician who was blinded to antiemetic drug assignment. There were no significant between-group baseline differences in age, gender, QTc interval before drug administration (mean=439 ± 29 ms), or characteristics of operative procedures and anesthesia techniques. Compared with baseline, mean maximal QTc lengthening was significant (P<0. Although the study was not designed to compare droperidol with ondansetron for duration of QTc lengthening, post hoc analysis found significant differences between the antiemetics. No ventricular arrhythmias occurred during the study period. We found no trials or observational studies that specifically assessed risk of arrhythmias associated with prophylaxis or treatment of postoperative nausea and vomiting with 5-HT3 antagonists. Children No comparative information on adverse events in children is available. In a placebo-controlled trial in children, the overall incidence of adverse events was 36% in the ondansetron group and 47% in the placebo group (P<0. Potentially drug-related headaches were reported in 3% of ondansetron-treated children and 2% of placebo- treated children (difference not significant). Patients undergoing radiation therapy Adults Direct comparisons Our post hoc analyses suggested no differences between oral granisetron 2 mg and oral ondansetron 8 mg in tolerability in 34 patients undergoing hyperfractionated total body 87 irradiation. Similar percentages of patients had adverse experiences that were possibly or probably related to study medication (39% compared with 25%, not significant). The most frequently reported adverse experiences were headache (28% compared with 18. Two patients in each treatment group experienced severe adverse events. Theses were both headache in the granisetron group and 1 episode each of severe infection and nervousness in the ondansetron group. Placebo-controlled and active-control trials Placebo-controlled and active-control trials of dolasetron, granisetron, and ondansetron were sufficiently heterogeneous in populations, compared drugs, radiation therapy regimens, and 2, 88-97 reporting of adverse events that meaningful indirect comparison was impossible. Antiemetics Page 40 of 136 Final Report Update 1 Drug Effectiveness Review Project 99 95 89-91, 98 Systematic reviews of earlier trials of granisetron and ondansetron concluded that these drugs are associated with increased incidence of headache and constipation. Additional placebo- 88 93, 94, 96, 97 controlled and active-control trials of granisetron and ondansetron also reported headache and constipation as being the most common significant adverse events. Pregnant patients Short-term tolerability In a study of ondansetron compared with promethazine in women with hyperemesis gravidarum, 172 significantly more women experienced sedation with promethazine than ondansetron. Long-term safety A prospective observational study assessed birth outcomes in women and infants exposed to 192 ondansetron during early pregnancy. The study enrolled 188 pregnant women with exposure to ondansetron during weeks 5 to 9 of gestation. The women had all been treated for nausea and vomiting associated with pregnancy. The study used 2 comparison groups, women exposed to other antiemetics during pregnancy and women exposed to other nonteratogenic drugs during pregnancy. Although it is stated that enrollment methods for all groups were the same, the total numbers enrolled and lost to follow-up in the control groups are not clear. No differences were found between groups in birth weight, number of live births, proportion of infants with deformities, or other measures.

There was no significant reduction in the primary endpoint (relative risk reduction, 6. There were no differences between groups on the individual components myocardial infarction or all-cause mortality, although the study was not powered to detect a difference on these endpoints. At 1 year of follow-up, there was no difference between groups in the occurrence of major coronary events. Despite greater lowering of low-density lipoprotein in the early intensive group, there were no differences between the early intensive and less aggressive groups on the primary endpoint (cardiovascular death, myocardial infarction, readmission for acute coronary syndrome, or stroke), or on any individual component of the primary outcome. Nine patients in the simvastatin only group developed myopathy (creatine kinase level greater than 10 times the upper limit of normal with associated muscle symptoms) while taking 80 mg compared with 1 patient in the placebo first group (P=0. Three of the 9 in the simvastatin group had creatine kinase levels higher than 10 000 units/L and met the definition for rhabdomyolysis. The rate of myopathy was high, despite the exclusion of patients at increased risk of myopathy due to renal impairment or concomitant therapy with agents known to enhance Statins Page 51 of 128 Final Report Update 5 Drug Effectiveness Review Project myopathy risk, or for having a prior history of nonexercise-related elevations in creatine kinase level or nontraumatic rhabdomyolysis. The lack of effect of more intensive treatment in this trial may have been due to several factors. The “early intensive” group started with only 40 mg of simvastatin, and did not increase to 80 mg for 30 days. Patients who were taking statin therapy at the time of their myocardial infarction (at randomization) were excluded. The study authors reported that the trial had less statistical power than originally planned due to a lower than expected number of end points and a higher than expected rate of study drug discontinuation. The large randomized trials summarized above provided strong evidence about the balance of benefits and harms from statin therapy. Because they were analyzed on an intention- to-treat basis, the benefits (reductions in coronary events, strokes, and, in some studies, mortality) in subjects who tolerated and complied with medication were diluted by the lack of benefit in subjects who discontinued medication because of side effects or did not complete the study for other reasons. Moreover, the mortality results of the trials indicated clearly that for the enrolled subjects and the duration of the trials, statins are beneficial. The balance of benefits and harms of statin drugs over a longer time than the trial durations remains unclear. Studies of the progression of atherosclerosis with secondary or incidental coronary heart disease endpoints Twelve studies of the effects of statins on progression of atherosclerosis also reported rates of 147-158 187 coronary or cardiovascular events. A head-to-head trial of the effect of atorvastatin 80 mg compared with pravastatin 40 mg on progression of atherosclerosis did not meet inclusion criteria because it did not report health outcomes. However, this study did meet inclusion criteria for Key Question 1 (see Evidence Table 1). In these studies, the primary endpoint was progression of atherosclerosis, and all of the patients had known coronary heart disease. To answer the question of whether treatment with a statin is associated with a reduction in clinical cardiovascular outcomes in patients with coronary heart disease, these studies were considered fair or fair-to-poor quality. In 6 of the 12 trials clinical outcomes were not a preplanned endpoint (they were "spontaneously reported"), and sample sizes were relatively small. Table 12 and Evidence Table 5 summarize the results of these studies. The number of trials and patients studied for each statin are as follows: fluvastatin (1 trial; N=429), lovastatin (3 trials; N=1520), pravastatin (5 trials; N=2220), and simvastatin (3 trials; N=1118). The information about fluvastatin was inconclusive and the other 3 statins were already known to be effective from better studies. In general, most trials in which coronary heart disease events were not a prespecified endpoint found a trend towards a reduction in clinical events in favor of a statin. In the trials in which coronary heart disease events were a secondary endpoint, there was usually a significant reduction in 1 of the components of coronary heart disease events. While consistent, the results of these studies are difficult to interpret because of possible reporting bias. That is, these trials may have been more likely to report a result if it was statistically significant or indicated a trend favoring treatment. Similar trials of progression of atherosclerosis that found no trend probably did not report coronary events.
