Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Patients were randomised to telephone contact or no telephone contact using a computer‐generated list of random numbers.
Allocation concealment (selection bias)	Unclear risk	Unclear if allocation concealed. Patients were randomised to telephone contact or no telephone contact using a computer‐generated list of random numbers.
Blinding of participants and personnel (performance bias) All Outcomes/Outcome 1	Low risk	Potentially unblinded but objective outcomes
Blinding of outcome assessment (detection bias) All Outcomes/Outcome 1	Unclear risk	Unclear if blinded assessors
Incomplete outcome data (attrition bias) All outcomes	Low risk	100% completion rate.
Selective reporting (reporting bias)	Unclear risk	Main outcomes reported
Other bias	Low risk	None
