Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Insufficient information to permit judgement, stratified for diabetes mellitus
Allocation concealment (selection bias)	Unclear risk	Insufficient information to permit judgement
Blinding of participants and personnel (performance bias) All outcomes	Low risk	Open‐label, however unlikely to have influenced the objective outcome measured
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Insufficient information to permit judgement
Incomplete outcome data (attrition bias) All outcomes	High risk	Dropout rates ‐ 38/64 (59%). Missing participants not accounted for. Per protocol analysis
Selective reporting (reporting bias)	High risk	No report of peritonitis or survival
Other bias	Unclear risk	Insufficient information to permit judgement
