Risk of bias in included studies
Cochrane Interactive Learning: module 5 - introduction to study quality and risk of bias
|Standard||Rationale and elaboration||Resources|
|Present at least one ‘Risk of bias’ table for each study that is included in a synthesis, with judgements about risks of bias, and explicit support for these judgements.||
‘Risk of bias’ presentation tools in RevMan should be used wherever possible.
MECIR conduct standard 52: Assess the risk of bias in at least one specific result for each included study. For randomized trials, the RoB 2 tool should be used, involving judgements and support for those judgements across a series of domains of bias, as described in Handbook (version 6).
|See Handbook (version 6) Section 7.1.2 and Chapter 8|
|R74||Summary assessments of risk of bias||Highly desirable|
|Present an overall risk of bias assessment across domains for each key outcome for each included study, and ensure that these are supported by the information presented in the ‘Risk of bias’ tables.||MECIR conduct standard 57: Summarize the risk of bias for each key outcome for each study.||See Handbook (version 6) Section 7.5 and Chapter 8|
|R75||Risk of bias in included studies||Mandatory|
|Provide a brief narrative summary of the risks of bias among the included studies.||It may be helpful to identify any studies considered to be at low risk of bias for particular key outcomes.|
