Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated randomisation
Allocation concealment (selection bias)	Low risk	The study statistician provided sequenced randomisation envelopes. The randomisation envelopes were opened by counsellors following the completion of each in‐hospital smoking cessation session. Counsellors then immediately informed the participant of their treatment condition.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Biochemically validated
Incomplete outcome data (attrition bias) All outcomes	Low risk	21.2 to 22.6% lost to follow‐up at 24 weeks post‐discharge
