Survival prediction for patients with malignant biliary obstruction caused by biliary tract cancer undergoing percutaneous biliary decompression

Figure 1 The modified Clinical Outcomes of Malignant biliary obstruction-Biliary tract cancer Survival nomogram for survival prediction. This nomogram was based on seven clinical predictors. To utilize these nomograms, the values of individual patients are plotted on each variable axis, with lines drawn to indicate the number of points assigned to each variable value. The sum of these numerical values is plotted on the total score axis, and three downward lines are drawn to the risk axis to determine the survival probabilities at 3-month, 6-month, and 1-year. PCC: Perihilar cholangiocarcinoma; DCC: Distal cholangiocarcinoma; ICC: Intrahepatic cholangiocarcinoma; GBC: Gallbladder cancer; TB: Total bilirubin; TC: Total cholesterol; Na: Serum sodium; Hb: Hemoglobin; CA199: Carbohydrate antigen 19-9.
