In Reply We appreciate the wide interest in our research article regarding the prevalence and treatment patterns of autism spectrum disorder (ASD) among children in the United States.1 Based on data from the 2016 National Survey of Children’s Health (NSCH), we estimated that the prevalence of ever-diagnosed ASD and current ASD was 2.79% and 2.50%, respectively. Among children with current ASD, almost 30% did not receive either behavioral or medication treatment. An independent analysis by Kogan et al2 has yielded virtually identical results, affirming the overall robustness of the national-level estimates in our study.
