Diagnostic value of RBP4 combined prognostic diagnosis model (A) Nomogram to predict overall survival time of HCC. To use this nomogram, the specific point for each variable of the patient lies on each variable axis. Draw a vertical line upward to determine the point at which each variable accepts; the sum of these points is located on the Total Points axis, and draw a vertical line down to the survival axis to determine the probability of 1- and 5- year overall survival time. The length of the line segment reflected the contribution of the factor to the final event. The sum of all individual scores corresponded to the corresponding 1-year and 5-year survival time. (B) ROC curve for HCC prognostic model (a, RBP4+other, AUC = 0.845, 95 % CI: 0.791∼0.899; b, RBP4+AFP+other, AUC = 0.926, 95 % CI: 0.888∼0.964; c, AFP, AUC = 0.809, 95 % CI: 0.747∼0.871).
