Wu 2009.

Methods	Study design: Randomized controlled trial Setting: Research unit for Asian health, NYC, USA Recruitment: via Asian Community Health Coalition member organizations
Participants	139 Chinese smokers (any smoking in previous wk); 12% women, av. age 44, av. cpd NS, 25% smoked < 10 cpd, 49% had never attempted to quit
Interventions	Therapist: Chinese speaking counsellor Pharmacotherapy: NRT. Patch for 8 wks (could start at any time in 6 m period) 1. Culturally‐tailored counselling in Chinese, 4 x 60 mins and S‐H 2. Health education in Chinese: 4 x 60 mins, including general health, nutrition, exercise and tobacco
Outcomes	Abstinence at 6 m (PP) Validation: CO < 6 ppm
Notes	New for 2016 update Conditions had same contact time, but control did not focus on smoking
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Randomized, method not stated
Allocation concealment (selection bias)	Unclear risk	Details not reported
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Biochemical validation of abstinence
Incomplete outcome data (attrition bias) All outcomes	Low risk	10% intervention and 14% control lost to follow‐up at 6 m and counted as smokers in ITT analysis
