Risk model and the Kaplan-Meier curves for the OS in CRC patients based on RAPGEF2 and its related genes. (a) Univariate Cox regression analysis demonstrated a substantial correlation between the identified genes and clinical prognosis. (b) The profile of LASSO coefficients for 21 OS-related genes and the perpendicular imaginary line were drawn at the value determined by 4-fold cross-validation. (c) To cross-validate the error curve, the tuning parameters (log) of OS-related proteins were chosen. Perpendicular imaginary lines were drawn at the ideal value using the minimum and 1-se criteria. (d) Analysis of the receiver operating characteristic curve in the training group. (e) Analysis of the receiver operating characteristic curve in the testing group.
