Anatomical specificity of post-stroke depression: Subcortical lesions, age-related patterns, and predictors of treatment response

Figure 2 Receiver operating characteristic curve analysis of the treatment response prediction model. The receiver operating characteristic curve demonstrates the discriminative ability of the multivariate logistic regression model for predicting treatment response. Area under the curve was 0.786 (95%CI: 0.728-0.844), indicating good predictive performance. The yellow star marks the optimal cutoff with maximum Youden index (0.449), corresponding to sensitivity of 74.2% and specificity of 70.7%. Diagonal dashed line represents random classifier (area under the curve = 0.50). Background shading indicates performance interpretation zones. AUC: Area under the curve.
