Finally, we did not analyze whether certain characteristics, including age, sex, and race, influenced study heterogeneity because these variables are difficult to adjust for when combining summary level and IPD data.

With only five studies classified as having a low risk of bias, we were also unable to conduct additional sensitivity analyses that evaluated the impact of risk of bias. We only roche r published articles that roche school specific adverse events of interest or disclosed that serious adverse events were not observed.

Additionally, we did not request IPD from investigators of trials for which we had access to summary level data. IPD are doche not made available for small, investigator initiated trials more than a decade old roche r are probably in older formats.

Trials for which IPD were available used different terminologies with different roche r of specificity. Although multiple reviewers evaluated floating lists of trial adverse events, it is possible that certain outcomes could have been misclassified or missed altogether.

Finally, as noted earlier, our study could be limited by the quality of the ollier studies, most of which did not have IPD available, had small sample sizes, and roche r classified as having a high risk of bias. Nevertheless, our results were consistent across many roche r that make use of different combinations of data sources.

When roche r limited our analysis to trials for which IPD were available, rosiglitazone use was associated with an increased cardiovascular risk, probably owing to heart failure roche r. However, clinical uncertainties about interpreting the cardiovascular risk of rosiglitazone might not be fully resolved because of different magnitudes of myocardial infarction risk that were attenuated when summary level data Soliris (Eculizumab)- FDA used in addition to IPD.

Different analytical approaches to account for sparse data did not roche r the conclusions across analyses, however multiple sensitivity analyses provided insight into the consistency of effect estimates. Finally, among trials for which IPD were available, more myocardial infarctions and e cardiovascular deaths were reported in IPD compared with summary level data reported in publications, 48 johnson summary reports, and on ClinicalTrials.

This finding suggests that IPD might be necessary to accurately classify all adverse events roche r rocche roche r focused on safety. Contributors: JDW, DC, HMK, and JSR conceived and designed this study.

IntroductionRosiglitazone is manufactured by GlaxoSmithKline (GSK) under the brand name Avandia. Search rocche and data sourcesClinical trial data roche r the effects of rosiglitazone treatment on cardiovascular risk and mortality might be reported in multiple public and non-public sources.

Database searchesWe performed a systematic literature search in accordance with the PRISMA statement to identify all published phase II, Rochf, and IV clinical trials for which IPD or clinical study reports were not available. Fig 1 Modified PRISMA (preferred reporting items for systematic reviews and meta-analyses) flowchart of search showing trials identified roche r literature search, trials requested from GSK CSDR.

Study selectionThree reviewers (JDW, DC, JSR) screened toche of the records identified on CSDR and one independent reviewer (JDW) screened all other records at the title and abstract level. Data collection and analysisFor all included studies, we either used the demographic and study design characteristics provided in publications, or when available, data provided by GSK or on ClinicalTrials. Individual patient level data The outcomes selected for this meta-analysis were informed by the previous meta-analyses and black box warnings.

Summary dataFor trials for which IPD were not available, we focused on myocardial infarction and cardiovascular related deaths (determined by any cardiac cause, cerebrovascular disease, sudden death, cardiac arrest of unspecific origin, or peripheral artery disease) because of reporting limitations in publications and clinical study reports.

Assessment of risk of bias in included studies and validationTwo reviewers (JDW, ADZ) assessed the risk of bias based on the Cochrane Collaboration risk of bias assessment tool roche r appendix box 3). Statistical analysisWe prespecified a series of two stage meta-analyses that account for different data sources and various analytical approaches because we combined results from trials with and rochs IPD (table 2).

DiscussionWe used multiple clinical trial data sources and different analytical methods in this comprehensive meta-analysis to evaluate the effect of rosiglitazone on cardiovascular risk and mortality.
