Since the publication of the article, the authors noticed that ‘NFI cohort’ and ‘NFI-free cohort’ columns in the ‘Autism^g’ and the ‘Autism/ADHD’ rows had been erroneously interchanged in Table 3. The updated table can be found below. This has now been updated in the HTML and PDF of the original article.

Table 3.
