Is nicotine replacement therapy for smoking cessation effective in the "real world"? : findings from a prospective multinational cohort study
(Disponible en anglais seulement.)
Nicotine replacement therapy (NRT) has been found in clinical trials to increase cessation. However, recent cross-sectional surveys have questioned whether NRT use by individuals who smoke making a quit attempt without supervision within clinical trials can be successful. Findings reveal NRT use without assistance was correlated with more long-term cessation.

Comment: RCTs are important, but I think the "real world" questions carries more weight with a lot of practitioners.
