Table 4 Receiver operating characteristic curve analysis results of two scales

Scale	AUC	95%CI	Optimal cutoff (points)	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)	+LR	-LR	Youden Index
HAMD-17	0.891	0.854-0.928	7	88.39	79.83	67.81	93.47	4.38	0.15	0.682
PHQ-9	0.867	0.826-0.908	7	83.04	81.12	67.88	90.87	4.4	0.21	0.642

Comparison of area under the curve between two scales, Z = 1.426, P = 0.154. AUC: Area under the curve; HAMD-17: 17-item Hamilton Depression Rating Scale; NPV: Negative predictive value; PHQ-9: Patient Health Questionnaire-9; PPV: Positive predictive value; +LR: Positive likelihood ratio; -LR: Negative likelihood ratio.
