Among them, rADCmin had the best diagnostic performance in differentiating low Ki-67 from high Ki-67 gliomas, with an AUROC of 0.778, a sensitivity of 76.60%, a specificity of 69.75%, a MCC of 0.329, and a Youden index was 0.463 (Table 3). This evidence concerns the gene MKI67 and central nervous system cancer.
