A Kaplan–Meier survival curve for death among cirrhotic patients stratified by tertiles of dietary protein intake (grams per kilogram body weight). The 4-year survival rate among patients across tertiles was 35%, 40%, 43%, respectively (log-rank test for homogeneity, P = 0.004). B Kaplan–Meier survival curve for death among cirrhotic patients stratified by tertiles of diary protein intake (grams per day). The 4-year survival rate among patients across tertiles was 32%, 40%, 43%, respectively (log-rank test for homogeneity, P = 0.001). C Kaplan–Meier survival curve for death among cirrhotic patients stratified by tertiles of vegetable protein intake (grams per day). The 4-year survival rate among patients across tertiles was 35%, 42%, 41%, respectively (log-rank test for homogeneity, P = 0.072). D Kaplan–Meier survival curve for death among cirrhotic patients stratified by tertiles of animal protein intake (grams per day). The 4-year survival rate among patients across tertiles was 42%, 38%, 37%, respectively (log-rank test for homogeneity, P = 0.296)
