IDH2 and neoplasm: In CGGA datasets, we adjusted for clinical factors such as age, sex, tumor grade, race, IDH2, and X1p19q2, and the multivariate Cox regression results also demonstrated that the radiosensitivity-related risk score was an independent prognostic factor for LGG (CGGA693: HR: 1.730, 95% CI: 1.215–2.463, p = 0.003; Figure 7C).
