Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Insufficient information to permit judgement
Allocation concealment (selection bias)	Unclear risk	Insufficient information to permit judgement
Blinding of participants and personnel (performance bias) All outcomes	High risk	Not blinded
Blinding of outcome assessment (detection bias) All outcomes	High risk	Not blinded
Incomplete outcome data (attrition bias) All outcomes	Low risk	Low dropout rate (6/101)
Selective reporting (reporting bias)	Low risk	All the outcomes were reported
Other bias	Unclear risk	No prophylactic antibiotic for exit site. The study reported the procedures were performed by trained nephrologists in the unit, but unclear about the grade and training experience of the procedurists
