Errors in Tables, Author Affiliation, and Online-Only Supplement

In the Original Investigation titled “Structural and Functional Brain Abnormalities in Attention-Deficit/Hyperactivity Disorder and Obsessive-Compulsive Disorder: a Comparative Meta-Analysis,”¹ published online June 8, 2016, and also in the August 2016 print issue of JAMA Psychiatry, there were errors in the tables, an author affiliation, and the online-only supplement. In Table 2, for the contrast ADHD decreased vs controls, the correct coordinates for the right caudate nucleus cluster are 18, 8, 14. For the left occipital lobe, the correct coordinates are −10, −94, 14. The correct coordinates for this contrast have also been added to eTable 8 in the Supplement. In Table 3, for the contrast ADHD decreased vs controls, the correct coordinates for the SMA/dmPFC cluster are −2, 10, 48, while for the contrast OCD increased vs controls the correct coordinates for the left insula/putamen/VLPFC/premotor cortex/postcentral/STL are −36, −10, 4.

The correct affiliation for Prof Mataix-Cols and Dr Radua was Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden.

Within the supplementary material, the study by Siniatchkin et al was previously missing from eTable 1 and eTable 11, while a duplicate entry for Banich et al has now been removed from eTable 11. The correct number of adult ADHD fMRI studies was 12 and pediatric VBM studies was 18. Within the first sentence of the eMethods section, the superfluous word “used” has been removed.

None of the findings or conclusions were affected by these errors. This article was corrected online. This article was also corrected in August 2017 to fix data in the abstract and Results section, as well as in Table 2.
