Sometimes an error persists beyond the BMJ and is noticed not by a reader or author but by one of our sister journals preparing the article for publication-in this case BMJ USA. In this Research Pointer by Carl van Walraven and colleagues (12 April, pp 791-2) we allowed a wrong confidence interval to slip through. In the last sentence in the first paragraph of the Methods section, the 95% confidence interval for the specificity (67%) of the ICD-9 codes should be 59% to 74% [not 79% to 94%].
