The lncRNA prognostic model. a Lasso-penalized Cox regression analysis of 17 DElncRNAs. Ten-fold cross-validation was applied to calculate the best lambda, which leads to a minimum mean cross-validated error. b The bar plot shows coefficients of three lncRNAs in the LPM. The color of the bars represented the P-value of the coefficients. c Risk score system of the LPM. The above scatter plot exhibits the risk scores of each KIRC patient with survival data, and the below heatmap displays the expression profiles of three lncRNAs in the LPM. K–M survival curves and time-dependent ROC curves of OS are shown in d and e, respectively. K–M survival curves and time-dependent ROC curves of DSS are demonstrated in f and g, respectively
