Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Randomisation was generated by a computer.
Allocation concealment (selection bias)	Low risk	Computer
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	This would be impossible
Incomplete outcome data (attrition bias) All outcomes	Low risk	All participants were reported
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Independent team
Selective reporting (reporting bias)	Low risk	All outcomes were reported
Protection against contamination bias	Low risk	There is no indication to suggest that the intervention was contaminated by the control group.
Other bias	Unclear risk	It is unclear if there are other risks not accounted for.
