*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group 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. |
1 Risk of bias: rated 'serious' ‐ randomisation methods not clearly stated; not all outcomes reported, not all participants accounted for. Only one small study included (Boyer 1987, n = 62). 2 Imprecision: rated 'very serious' ‐ few participants, few events, leading to uncertainty in the precision of estimate of effect. 3 Control risk: mean baseline risk presented from single study. 4 Risk of bias: rated 'serious' ‐ randomisation methods not clearly stated; not all outcomes reported, sponsored by pharmaceutical company. Only one small study included (Saletu 1994, n = 40).
