LASSO COX regression for the OS- and DFS-predicting models based on radiomics features extracted from nephrographic (A), corticomedullary (B) and unenhanced (C) phase and transcriptome mRNA level (D). Left plot of each model: The dotted vertical line was plotted at the value selected by the 10-fold cross-validation based on the minimum criteria (the value of lambda with the lowest partial likelihood deviance). Right plot of each model: Selection of the tuning parameter (lambda) in the LASSO regression via 10-fold cross-validation based on minimum criteria. LASSO: Least absolute shrinkage and selection operator; OS, Overall survival.
