  • The risk in the intervention group (and its 95% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).

  • GRADE, Working Group grades of evidence.

  • High certainty: We are very confident that the true effect lies close to that of the estimate of the effect.

  • Moderate certainty: We are moderately confident in the effect estimate. The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different.

  • Low certainty: Our confidence in the effect estimate is limited. The true effect may be substantially different from the estimate of the effect.

  • Very low certainty: We have very little confidence in the effect estimate. The true effect is likely to be substantially different from the estimate of effect.

  • *Downgraded 1 for serious risk of bias.

  • †Downgraded 1 for inconsistency due to moderate heterogeneity.

  • ‡Downgraded 1 for imprecision due to Trial Sequential Analysis showing that there was not enough information to confirm or reject a RRR of 15%. Moreover, the meta-analysis showed wide CI.

  • RR, risk ratio; ARNI, angiotensin receptor blocker neprilysin inhibitor; RCTs, randomised controlled trials.
