Effectiveness of Varenicline Versus Combination Nicotine Replacement Therapy for Smoking Cessation: One-Year Outcomes in a Smoking Cessation Clinic in Taiwan.

Network meta-analysis of randomized trials suggests that varenicline and cNRT are similarly effective for smoking cessation. This study shows that 1-year sustained abstinence rates were significantly higher among smokers using varenicline, compared with smokers using cNRT, when used as part of a structured smoking cessation program. These findings are highly relevant to policy makers and service providers to help determine provision of smoking cessation treatment.
