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.

在题为“注意力缺陷/多动障碍和强迫症的结构和功能性大脑异常：强迫症：一种比较荟萃分析”的原始调查中，¹在2016年6月8日在线发布，并于2016年8月出版的《美国医学会杂志》（JAMA Psychiatry），结果报告中有错误。注意缺陷/多动障碍功能磁共振成像荟萃分析中所包括的患有缺陷/多动障碍和健康对照的正确人数分别为541和620。表1中给出了这些值，但摘要和结果部分的文本中包含了不正确的数字。此外，强迫症功能磁共振成像研究中正确的对照数目为284。最后，表2中以“（28，4，2）”给出的簇应以“（--28，4，2 2）。” 这些错误均不会影响本文的任何发现。本文已在线更正。
