To assess the risk of bias, at least two review team members assess each included article independently using a previously selected tool. To resolve discrepancies, the team may use รขโ‚ฌยฆ Several approaches for assessing risk of bias due to missing results have been suggested.

The chapter discusses two means of reducing, or potentially avoiding, bias due to missing results. It also describes a framework for assessing the risk of bias due to missing results in a synthesis. We start by discussing approaches for avoiding or minimizing bias due to missing results in systematic reviews in section 13. 2, and provide guidance for assessing the risk of bias due to missing results in รขโ‚ฌยฆ In this paper, the authors evaluated standard error, precision (inverse of standard error), variance, inverse of variance, sample size and log sample size (vertical axis) and log odds ratio, log รขโ‚ฌยฆ We start by discussing approaches for avoiding or minimizing bias due to missing evidence in systematic reviews in section 13. 2, and provide guidance for assessing the risk of bias due to รขโ‚ฌยฆ Risk of bias assessment (sometimes called quality assessment or critical appraisal) helps to establish transparency of evidence synthesis results and findings.
