Notably, the accuracy in diagnosing IDH-mutant astrocytoma, oligodendroglioma, and IDH-wildtype glioblastoma was 0.66 (95% CI = 0.56–0.74) and F1 scores for each tumor class were 0.70 (95% CI = 0.58–0.80), 0.62 (95% CI = 0.46–0.76), and 0.64 (95% CI = 0.49–0.76), respectively (sample size N = 108). Here, IDH1 is linked to glioblastoma.
