Correction to: British Journal of Cancer (2006) 95, 363–365. doi:10.1038/sj.bjc.6603250

Owing to an author error, there was a mistake in the presentation of results in Table 1 in the above paper. All figures in the table were correct, but the number of cases, person-years and rate ratios presented for NSAID users with 2–9 prescriptions were those pertaining to NSAID users with 10+ prescriptions, and vice versa. Correction of this interchange of results has no implications for the presentation of results in the article text, and conclusions and abstract remain the same. The correct Table 1 is shown below.
