Dynamic ultrasound monitoring of intraperitoneal effusion for predicting complications after laparoscopic gastrectomy

Figure 3 Receiver operating characteristic curve of diagnostic efficiency. Receiver operating characteristic curves show the predictive performance of procalcitonin, C-reactive protein levels and white blood cell counts. The combined model (procalcitonin + mixed effusion) demonstrated superior predictive efficacy (area under the curve = 0.912) compared to the individual markers. CRP: C-reactive protein; PCT: Procalcitonin; WBC: White blood cell count; AUC: Area under the curve.
