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	Unclear risk	Insufficient information to permit judgement
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Blinding not discussed, but outcome measurements are unlikely to be affected by the lack of blinding.
Incomplete outcome data (attrition bias) All outcomes	Low risk	All patients were followed up
Selective reporting (reporting bias)	Low risk	Study outcomes were appropriate, and concisely reported
Other bias	Unclear risk	As this is only an abstract, thorough analysis of biases is impossible
