aThe 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, OR Odds 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

bAssumed Risk is based on the default calculation within GRADEpro (mean control group risk, and median control group risk)

cAssessment based on three studies thus precision cannot be accurately determined

dSeveral included studies had 3 or more high risk of bias assessments

eStatistical heterogeneity I2 = 94 %

fDisease targets are an indirect estimate of patient important outcomes

gStatistical heterogeneity I2 = 70 %

hStatistical heterogeneity I2 = 41 %

iStatistical heterogeneity I2 = 60 %

jStatistical heterogeneity I2 = 95 %

kOverall estimate has large range for 95 % confidence interval
