Combined transcranial direct current and repetitive transcranial magnetic stimulation for adolescent non-suicidal self-injury

Figure 1 Receiver operating characteristic curve analysis of the prediction model for treatment response. The area under the curve (AUC) was 0.782 (95% confidence interval: 0.724-0.840). At the optimal cutoff point (marked by the solid circle), the sensitivity was 72.6%, specificity was 71.4%, and Youden index was 0.440. The dashed diagonal line represents the reference line (AUC = 0.5). AUC: Area under the curve; CI: Confidence interval.
