However, for the RSF after imputation (Fig 6), the top 20 genes/ covariates strongly related to CRC identified using RSF with log-rank split-rule are age, stages, molecular subtype, PIPOX, ADPRM, CLCN2, RPS27L, IER5, POLR3B, SLC6A4, KRAS, SGMS2, DUSP4, SLC28A3, SLC9A8, ACOT8, SYTL1, CABLES2, SCAND1, and MAP7D2. Here, KRAS is linked to colorectal carcinoma.
