*Serious risk of bias due to serious confounding reported in both studies implemented for this outcome according to ROBINS-I tool for observational studies.
† Serious imprecision due to low optimal information size. The total number of patients included is less than the number of patients generated by a conventional size sample calculation for a single adequately powered clinical trial.
‡Serious risk of bias due to serious confounding reported in studies implemented for this outcome according to ROBINS-I tool for observational studies.
