Novel prognostic score based on the preoperative total bilirubin-albumin ratio and fibrinogen-albumin ratio in ampullary adenocarcinoma

Figure 1 Volcano plot showing the cutoff values of total bilirubin-albumin ratio and fibrinogen-albumin ratio through the best survival separation model. A: Total bilirubin-albumin ratio; B: Fibrinogen-albumin ratio.

Figure 2 Spearman correlations between preoperative carbohydrate antigen 199, carcinoembryonic antigen, alanine aminotransferase, aspartate aminotransferase, total bilirubin-albumin ratio and fibrinogen-albumin ratio. A: Total bilirubin-albumin ratio; B: Fibrinogen-albumin ratio. AST: Aspartate aminotransferase; ALT: Alanine aminotransferase; CEA: Carcinoembryonic antigen; CA199: Carbohydrate antigen 199.

Figure 3 Comparing the Kaplan-Meier survival curves of different groups divided by total bilirubin-albumin ratio, fibrinogen-albumin ratio and total score. A: Total bilirubin-albumin ratio; B: Fibrinogen-albumin ratio; C: Total score. TBAR: Total bilirubin-albumin ratio; FAR: Fibrinogen-albumin ratio; OS: Overall survival.
