Specific mean AUROCs per tumor type were 0.82 (95% CI = 0.66–0.98) for IDH mutant gliomas, 0.71 (95% CI = 0.53–0.90) for IDH wildtype gliomas, 0.89 (95% CI = 0.8–0.97) for meningiomas, 0.95 (95% CI = 0.73–1.00) for hemangiopericytomas and 0.93 (95% CI = 0.8–1.0) for low grade glioneuronal tumors. This evidence concerns the gene IDH1 and meningioma.
