Fig. 1From: Preoperative albumin-to-fibrinogen ratio predicts severe postoperative complications in elderly gastric cancer subjects after radical laparoscopic gastrectomyPredictive value of AFR for SPCs in GC patients by ROC curve analysis. The results indicated preoperative AFR as a potential predictive factor for SPCs in GC patients with an AUC of 0.841, 95%CI of 0.783–0.900, a cut-off value of 8.49, a sensitivity of 76.36% and a specificity of 80.77%, respectively (P < 0.001). AFR, albumin-to-fibrinogen ratio; SPCs, severe postoperative complications; GC, gastric cancer; ROC, receiver operating characteristic; AUC, the area under the curve; CI, confidence intervalBack to article page
