Figure 5.

Kaplan–Meier plots for each mutation-positive group (A–C) separated into two subgroups by their radiomic scores (higher than or lower than the median radiomic score for each mutation-positive group). The subgroup with radiomic score values higher than the median radiomic score of each mutation-positive group had significantly shorter survival duration than the subgroup with values lower than the median radiomic score. The radiomic scores were computed as the weighted average of the features shown in Table 4 (weighted by Cox regression coefficients).
