An error occurred in the article by Goyal et al, titled “State Gun Laws and Pediatric Firearm-Related Mortality,” published in the August 2019 issue of Pediatrics (2019;144[2]: e20183283; doi:10.1542/peds.2018-3283). On Table 3, the column 4 header read “Predicted Mortality (95% CI).” It should have read “aIRR (95% CI).” The online article has been amended.
