- aCertainty of evidence downgraded due to concerns of poor comparability between study cohorts
- bCertainty of evidence downgraded for imprecision, due to few events and wide confidence intervals
- cCertainty of evidence downgraded for inconsistency due to significant heterogeneity that remained unexplained (ranged between 67% and 98%)
- dCertainty of evidence not downgraded due to significant heterogeneity being explained by surgical disciplines and higher prevalence of diabetes in kidney transplant patients
- eCertainty of evidence upgraded due to large (>5 fold) risk estimate
- fCertainty of evidence upgraded due to large (>2 fold) risk estimate
- g Publication bias not judged to assess certainty of evidence due to small study numbers (<10)
- hCertainty of evidence not downgraded for imprecision due to significant number of events in both groups
