In the article that appeared on page 84 of the January 2011 issue, the Results section of the abstract contained three unintended odds ratios and 95% confidence intervals. The Results section should have appeared as follows:

Results:  Of 1,238,171 surgical patients undergoing general anesthesia, we identified 17 MH patients. Only one in-hospital death was identified. Men were significantly more likely to contract MH (odds ratio: 3.49; 95% CI 1.14–10.7; P = 0.029). No MH patient was found among 19,871 suxamethonium users. The prevalence of MH was relatively high in users of sevoflurane and rocuronium compared with nonusers but was not statistically significant.
