The new Cochrane risk of bias tool (RoB2) to assess risk of bias in randomized trials
A good systematic review synthesizes results of unbiased studies. If included studies are biased; however, the review risks presenting a summary estimate that is statistically precise, and thus often perceived as trustworthy, but which systematically deviates from the truth. The most frequently used tool to assess risk of bias in randomized trials is the Cochrane risk of bias tool which was published in a revised version in 2019, RoB2. I will present the various meaning of the term ‘bias’, and relate the concept to statistical precision and heterogeneity, provide an overview of the main new aspects of RoB2, and discuss the strengths and weaknesses of how risk of bias in included trials is conducted in current reviews.
