AWGS2019 vs EWGSOP2 for diagnosing sarcopenia to predict long-term prognosis in Chinese patients with gastric cancer after radical gastrectomy

Figure 3 The higher the concordance index (P < 0. 001), the lower the Akaike information criterion, and the higher area under time-dependent receiver operating characteristic curve of AWGS2019-sarcopenia model reflects a more accurate model in predicting the long-term overall survival than EWGSOP2-sarcopenia model. A: Concordance index for overall survival in patients with AWGS2019 and EWGSOP2; B-D: Time-dependent area under time-dependent receiver operating characteristic curve for overall survival in patients with AWGS2019 and EWGSOP2 at 1 year (B), 3 years (C), and 5 years (D). AUC: Area under the curve; ROC: Receiver operating characteristic; C-index: Concordance index.
