*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The effect with a PIL developed with feedback from users (and its 95% confidence interval) is based on the assumed risk in the comparison group (usual PIL) and the relative effect of the intervention (and its 95% CI). CI: confidence interval; RR: risk ratio. | |||||
GRADE Working Group grades of evidence High quality: further research is very unlikely to change our confidence in the estimate of effect. Moderate quality: further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Low quality: further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. Very low quality: we are very uncertain about the estimate. |
aThis is the baseline recruitment measured in the studies presented in the 'Summary of findings' table. bWe selected the low, moderate and high illustrative recruitment levels of 10%, 30% and 50% based on our prior experience with trial recruitment. cWe downgraded evidence by 1 level because of indirectness: Chen 2011 actually measures entry to pre‐randomisation phase, not recruitment.
