Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	'The PI used computer generated randomization lists so that randomization was stratified by the RT [respiratory therapist] and subjects were allocated to treatment condition using blocks of four.'
Allocation concealment (selection bias)	Low risk	'Randomization took place after the RT collected baseline data, provided bedside counselling, and obtained consent; thus RTs were blind to group assignment during those procedures.'
Incomplete outcome data (attrition bias) All outcomes	Low risk	37.5% I, 43.6% C lost at 6m, similar between groups. Counted as smokers in MA
