Errors in Results and Tables

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 reporting of the results. The correct numbers of patients with attention-deficit/hyperactivity disorder and healthy controls included in the attention-deficit/hyperactivity disorder functional magnetic resonance imaging meta-analysis are 541 and 620, respectively. These values are given in Table 1, but incorrect numbers were included in text in the abstract and Results section. Moreover, the correct number of controls in the obsessive-compulsive disorder functional magnetic resonance imaging studies is 284. Finally, the cluster given in Table 2 as “(28, 4, 2)” should be given as “(−28, 4, 2).” None of the findings from this article are affected by these errors. This article was corrected online.
