Bala MM, Akl EA, Sun X, et al. Randomized trials published in higher vs. lower impact journals differ in design, conduct, and analysis. Journal of Clinical Epidemiology 2013 (66):286-295
Rigorously designed and conducted randomized controlled trials (RCTs) provide high-quality evidence regarding the effects of health care interventions. This study examined and compared the study design, conduct, analysis and/or reporting of a large cohort of RCTs published in higher vs. lower impact journals. Results showed that RCTs published in higher impact journals were less prone to risk of bias.
