Eight were excluded. 27 smokers were allocated to the group behaviour intervention and vanrenicline, another 25 smokers were allocated to the control group; More participants had quit at 4 weeks in the group behaviour intervention compared to the control group: 70.3% vs 52%, p>0.05; 62.9% vs 32% at 12 weeks, p<0.05; Reported quit rates remained high difference at 6 months, but there was some uncertainty about between group differences because of incomplete follow up.
