Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Random number table.
Allocation concealment (selection bias)	Unclear risk	No information provided.
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Not feasible due to nature of intervention
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not described
Incomplete outcome data (attrition bias) All outcomes	Low risk	ITT nor reported, bu seems reasonable as the numbers in both groups are equal to randomised numbers. missing outcome data mentioned.
Selective reporting (reporting bias)	Low risk	All primary and secondary outcomes are reported as pre‐specified.
Other bias	Low risk	No other bias detected
