The irlncRNA signature distribution and survival of patients in the training cohort. a LASSO Cox coefficient profiles of the selected prognostic irlncRNAs. b Correlation between the expression of selected irlncRNAs and risk score. c Risk score distribution with patient survival status in the training cohort, with red color indicating that patients have died and blue color indicating survival. Expression distribution of the eight irlncRNAs in the training cohort, with red color indicating higher expression and blue indicating lower expression. d Kaplan–Meier curves of OS in 48 patients from the training cohort based on risk score. e ROC analysis of the irlncRNA signature for prediction of survival at 1, 3, and 5 years in the training cohort
