  • *Downgraded due to being a surrogate outcome.

  • †Downgraded due to potential for a recommendation or clinical course of action differing if the upper versus the lower boundary of the CI represented the truth and/or a sample size <400.

  • ‡Publication bias suspected after inspection of funnel plots.

  • §Inconsistent due to high heterogeneity, non-overlap of CI and/or markedly dissimilar point estimates.

  • ¶Risk of bias was judged to be high.

  • LT, long term; MD, mean difference; MT, medium term; RCTs, randomised controlled trials; ST, short term.
