Incidence and risk factors of post-traumatic stress disorder in patients after endoscopic submucosal dissection for early gastric cancer

Figure 1 Receiver operating characteristic curves for post-traumatic stress disorder prediction. Receiver operating characteristic curves comparing the combined 6-factor model with individual risk factors. The combined model [area under the curve (AUC) = 0.856] outperformed all individual predictors, with Social Support Rating Scale (AUC = 0.745) and Self-Rating Depression Scale (AUC = 0.681) being the strongest single predictors. AUC: Area under the curve; CI: Confidence interval; SSRS: Social Support Rating Scale; SDS: Self-Rating Depression Scale.
