late AO OCD vs. HC in 0.73 (95% CI = 0.67–0.79; pcorrected < 0.001), and early vs. late AO in 0.81 (95% CI = 0.74–0.88; pcorrected < 0.001). As no late AO patients were present in pediatric samples, classifications were re-run on adult samples only, resulting in 0.65 AUC (95% CI = 0.57–0.72;pcorrected = 0.01) for early AO vs. HC, 0.70 (95% CI = 0.63–0.76; pcorrected < 0.001) for late AO vs. HC, and 0.73 (95% CI = 0.64–0.82;pcorrected < 0.001) for early vs. late AO. Classification of short disease duration OCD vs. HC resulted in 0.68 AUC (95% CI = 0.61–0.75;pcorrected < 0.001), long disease duration vs. HC in 0.71 (95% CI = 0.65–0.78; pcorrected < 0.001), and short vs. long duration in 0.78 (95% CI = 0.7–0.85; pcorrected < 0.001). Finally, low severity OCD vs. HC classification resulted in 0.60 AUC (95% CI = 0.53–0.67; pcorrected = 0.15), high severity OCD vs. HC in 0.61 (95% CI = 0.54–0.68; pcorrected = 0.04), and low vs. high severity OCD in 0.58 (95% CI = 0.49–0.66; pcorrected = 1).
