As Table 2 describes, though all the sixteen biomarkers might perform well in recognizing ACCs from alive ACC samples (the average accuracy ≥ 0.70), four MPBs including ASPM (average accuracy = 0.8228), BIRC5 (average accuracy = 0.8059), CCNB2 (average accuracy = 0.8080), and CDK1 (average accuracy = 0.8080) were screened out for more accurate prediction of OS. Here, CDK1 is linked to adrenal cortex carcinoma.
