Risk of Bias in Iranian Randomized Trials Included in Cochrane Reviews.

ABSTRACT:

Background

Among interventional studies, randomized controlled trials (RCTs) provide the highest level of evidence. However, RCTs can be susceptible to the risk of bias (RoB). Systematic reviews can be performed to appraise RoB in the included articles using evaluative tools. This study aimed to describe the main characteristics and focus on the RoB of RCTs conducted in Iran and included in Cochrane Reviews (CRs).

Methods

We searched "Iran" by selecting the "Search All Text" and "Review" fields in the Cochrane Database of Systematic Reviews within Ovid. CRs that included the RCTs conducted in Iran were retrieved.
