p < .05 (Holm-adjusted across outcomes);

^†Significant difference between model predicted and actual values for participants with predictor value of zero;

^aCYBOCS change baseline to post-treatment (lower values indicate greater symptom reduction);

^bCGI-I post-treatment (lower values indicate greater global improvement);

^cTreatment Responder (higher values indicate greater odds of treatment response)
