Carbon cost of pragmatic randomised controlled trials: retrospective analysis of sample of trials.

28 Oct 2009 OBJECTIVE: To calculate the global warming potential, in carbon dioxide (CO(2)) equivalent emissions, from a sample of pragmatic randomised controlled trials. DESIGN: Retrospective analysis. Data source Internal data held by NIHR Evaluation, Trials ... Read more...

Reporting of safety results in published reports of randomized controlled trials.

24 Oct 2009 BACKGROUND: Reports of clinical trials usually emphasize efficacy results, especially when results are statistically significant. Poor safety reporting can lead to misinterpretation and inadequate conclusions about the interventions assessed. Our ... Read more...

Baseline characteristics and statistical power in randomized controlled trials: selection, prognostic targeting, or covariate adjustment?

29 Sep 2009 OBJECTIVE: Heterogeneity of patients is a common problem in randomized controlled trials (RCTs) in various fields of clinical research. We aimed to investigate the potential benefits of different approaches for dealing with heterogeneity in a case ... Read more...
