Correction: How effective is nicotine replacement therapy in helping people to stop smoking?

An author's error and two editorial errors occurred in this article by Tang et al (1 January, 21-6). The last sentence of the first paragraph of the Results section should read "among the 15 trials of invited subjects" (not 14 as given). In table IV, Blondal's study had 28 subjects given placebo gum, and 1 (4%) quit smoking (these numbers are missing from the table).
