*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; h: hours; 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. |
*Assumed risk was derived from the event rates in the comparator groups aDowngraded by two levels because of serious imprecision (see Appendix 12) bDowngraded by two levels because of risk of performance bias and imprecision (see Appendix 12) cDowngraded by three levels because of risk of performance bias and serious risk of imprecision (see Appendix 12) dDowngraded by two levels because of serious risk of imprecision (see Appendix 12)
