Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: "Eligible patients were assigned to an intervention or control group in a randomized, parallel design fashion and followed over a 4‐month period". Unclear how randomisation took place
Allocation concealment (selection bias)	Unclear risk	Allocation procedure not described explicitly. No information provided
