Risk of bias was assessed using the QUIPS checklist. Downgraded by 1 increment if the majority of the evidence was at high risk of bias and downgraded by 2 increments if the majority of the evidence was at very high risk of bias.
Default MID used to assess imprecision. Downgraded by 1 increment if the confidence interval crossed one MID or by 2 increments if the confidence interval crossed both MIDs. GC considered the clinical importance of the effect estimate for each analysis on a case by case basis, taking into consideration the increment of the risk factor and the outcome under study.
