In the Original Investigation titled “Psychotherapies for Generalized Anxiety Disorder in Adults: A Systematic Review and Network Meta-Analysis of Randomized Clinical Trials,” published online October 18, 2023, the authors had erroneously included a secondary analysis of a primary trial already included in the network, thus counting the same cohort of patients twice. Additionally, a standard error had been misinterpreted as a standard deviation during data extraction. All analyses have been rerun, and the article was corrected to fix errors in the Abstract, Key Points, text, References, Table 2, Figures 1-3, and eAppendixes D-N in Supplement 1. The 95% CI for behavior therapy vs waiting list no longer crosses the line of no effect in the primary efficacy analysis, but overall, the corrections do not affect the clinical interpretations or conclusions. The article was corrected online.
