Incorrect Sample Size in a Table

In the Original Investigation titled “Difference-in-Differences Analysis of the Association Between State Same-Sex Marriage Policies and Adolescent Suicide Attempts,” published in the April issue of JAMA Pediatrics,¹ an incorrect sample size appeared in Table 2. In the first column of that table, the sample size for all students, which was given as 765 039, should be replaced with 762 678. This article was corrected online.
