Errors in the Results and Supplement

In the Original Investigation titled “Development of Proteomic Prediction Models for Transition to Psychotic Disorder in the Clinical High-Risk State and Psychotic Experiences in Adolescence,”¹ which published in the January 2021 issue, there were errors in the Results and eTable 9 in the Supplement. In the ELISA Validation section in the Results, the last sentence should be the following: “The A2M [alpha-2-macroglobulin] mean in CHR-T [participants at clinical high risk who transitioned to first-episode psychosis] was 1173.1 μg/mL vs 1501.7 μg/mL in CHR-NT [participants at clinical high risk who did not transition to psychosis] (FDR [false discovery rate]-corrected P = .02), and the C1r mean in CHR-T was 65 008.9 μg/mL vs 52 803.9 μg/mL in CHR-NT (FDR-corrected P = .04).” In the Supplement, the first value in the CHR-NT mean (SD) column should be 1501.7 (711.1).
