¹This table evaluates the predictive efficacy of individual indicators and the combined model for depression in acute intracerebral hemorrhage survivors by receiver operating characteristic curve analysis. Area under the curve, sensitivity, specificity and 95% confidence interval were calculated to assess discriminatory power. The results showed that the combined model had the highest area under the curve (0.885), with sensitivity of 93.3% and specificity of 67.0%, indicating better predictive efficacy than single indicators (P < 0.001).

AUC: Area under the curve; CI: Confidence interval.
