Kaplan-Meier curve of the cohort stratified by radiomic risk score (A) and pMGMT methylation status (C). Both stratifications identified the poor-risk subgroup within the cohort. P values were calculated with the Log-rank test. LASSO was further used to predict long-term survivors using various cut-off in overall survival (B). In this analysis, predictive modeling was possible only when the cut-off was set within 10 to 17 months.
