The use of smoking cessation treatments improved smokers' chances of quitting, a systematic review and meta-analysis showed.
Both nicotine replacement therapy (NRT) and bupropion were superior to placebo in helping patients quit (odds ratio [OR] for NRT 1.84, 95% CI 1.71-1.99; OR for bupropion 1.82, 95% CI 1.60-2.06), wrote Kate Cahill of the University of Oxford in England, and colleagues.
