Receiver operator characteristic (ROC) curve for the Chinese entrapment scale as a predictor of depression. The area under the ROC curve was 0.854 (95% confidence interval: 0.809, 0.892). The optimum cut-off value of the ES for predicting depression was 23 with a sensitivity of 70% and specificity of 85.4% when a PHQ-9 score > 9 was considered to indicate depression
