From: Rethinking the assessment of risk of bias due to selective reporting: a cross-sectional study
Characteristics | Number (%), of n = 100 |
---|---|
Number of included studies | |
Total number of studies included in review, median (IQR) | 13 (7–32) |
Number of studies per review at high risk of outcome non-reporting bias, Median (IQR) | 2 (1–5) |
Percentage of studies per review at high risk of outcome non-reporting bias, Median (IQR) | 20 (11–39) |
High risk outcome(s) stated in the risk of bias table | |
One non-/partially reported outcome clearly specified | 27 (27) |
More than one non-/partially reported outcome clearly specified | 52 (52) |
No outcome specified (e.g. only stated that “Some outcomes were not reported”) | 21 (21) |
Reviewer-perceived importance of high-risk outcome(s) | |
At least one was a primary review outcome | 52 (66)^{a} |
All were secondary review outcomes | 27 (34)^{a} |
Synthesis of high-risk outcome(s) | |
At least one outcome was synthesised in a meta-analysis (based on data from studies that completely reported the outcome) | 51 (65)^{a} |
All outcome(s) were synthesised/summarised narratively | 28 (35)^{a} |
Location in the review where the synthesis of at least one high-risk outcome was reported | |
Main text | 79 (100)^{a} |
