Coding Error in Analysis of Rotavirus Vaccination and Type 1 Diabetes

JAMA Pediatr. 2019;173(9):895. doi:10.1001/jamapediatrics.2019.2523

In the article titled “Association of Rotavirus Vaccination With the Incidence of Type 1 Diabetes in Children,” published online January 22, 2019, and in the March 2019 issue of JAMA Pediatrics,1 an incorrect code was used to identify the total number of cases with type 1 diabetes. All analyses were recalculated after correcting the error. The mean rate of cases per 100 000 children changed from 12.7 (95% CI, 11.0-14.8) to 24.4 (95% CI, 22.4-26.7), and in children aged 0 to 4 years, the number of incident cases of type 1 diabetes changed from a decrease of 14% (rate ratio, 0.86; 95% CI, 0.74-0.99; P = .04) to a decrease of 15% (rate ratio, 0.85; 95% CI, 0.75-0.97; P = .02). All values in the Table and Figure were recalculated. Importantly, none of the study’s conclusions were affected.2 This article was corrected online.
