Figure 7 of a recent meta-analysis examining smoking cessation therapies1 contains 2 errors. First, the second and third columns should have been labelled “Bupropion” and “Varenicline,” respectively. Second, varenicline was inadvertently compared with placebo rather than with bupropion, the intended comparator. The authors' revised analysis suggests that varenicline therapy may increase the proportion of patients who are abstinent compared with bupropion therapy; however, the credible interval (CrI) is wide, and these results are not definitive (odds ratio 1.40, 95% CrI 0.75–2.66) (Figure 1). All the other analyses presented in this article have been re-verified.
