The authors of this research paper have alerted us to some errors in table 2, which presents a comparison of baseline characteristics by treatment group (BMJ 2012;344:e1696, doi:10.1136/bmj.e1696). The total (n=2591) values for the rows that list previous smoking support are incorrect and should have read: for nicotine replacement therapy without prescription 516 (19.9), for nicotine replacement therapy from health professional 123 (4.7), for bupropion 27 (1.0), for varenicline 60 (2.3), for NHS Stop Smoking Service 21 (0.8), for other quitline 2 (<0.1), and for other 30 (1.1). The smoking support service NHS 1 to 1 was included in the table in error and should be ignored. These inaccuracies do not affect the rest of the paper.
