Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "randomized with a computer‐generated table of random numbers" (p. 212 Par 6)
Allocation concealment (selection bias)	High risk	Use of an open random allocation schedule (e.g. random‐number table)
Blinding of participants and personnel (performance bias) All outcomes	High risk	Study participants and personnel were not blinded
Blinding of outcome assessment (detection bias) All outcomes	High risk	No blinding of outcome assessment
Incomplete outcome data (attrition bias) All outcomes	Low risk	No missing data
Selective reporting (reporting bias)	Unclear risk	Insufficient information to permit judgment of 'low' or 'high' risk
Other bias	Unclear risk	Insufficient information to assess whether an important risk of bias exists
