Correction
At the time the article “Risk of Death From Accidental Overdose Associated With Psychiatric and Substance Use Disorders,” by Amy S.B. Bohnert et al., was published online on September 28, 2011, Tables 1 and 2 contained several errors in hazard ratios and confidence intervals, some of which were repeated in the abstract and in the Results section. The errors in Table 1 were in the percentage of all patients in the 60–69 age group (the correct number is 19.8) and in the confidence interval for the 70–79 age group (the correct range is 0.16–0.28). The errors in Table 2 are highlighted [in the correction's PDF].
These errors were corrected for the article's print appearance in the January 2012 issue and for its online posting as part of that issue. None of the errors affected the study findings.
