Trial Sequential Analysis for complete versus culprit‐only revascularisation on long‐term all‐cause mortality. The diversity‐adjusted required information size (DARIS) was calculated based on an expected relative risk reduction (RRR) of 20% from proportion event in control (Pc) group of 6.3% with an alpha of 2% and beta of 10%.

*The risk in the intervention group (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; MVD: multi‐vessel disease; RCT: randomised controlled trial; RR: risk ratio; STEMI: ST elevated myocardial infarction.

GRADE Working Group grades of evidence
High quality: We are very confident that the true effect lies close to that of the estimate of the effect.
Moderate quality: 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 quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect.
Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect.

1 Downgraded due to publication (reporting) bias.

2 Downgraded due to study limitations (largely risk of attrition bias and selection bias).

3 Downgraded because of indirectness: black and Hispanic people, as well as women were under‐represented.

4 Downgraded due to imprecision.
