PGK1 and adrenal cortex carcinoma: As shown in Figure 2(b), PGK1 upregulation was indicative of unfavorable PFI for ACC (p = 0.0018), BRCA (p < 0.0001), CESC (p = 0.00034), HNSC (p < 0.0001), KICH (p < 0.0001), MESO (p = 0.00078), PAAD (p = 0.00096), and PRAD (p = 4e − 04) but its upregulation indicated favorable PFI for patients with KIRC (p < 0.0001) and STAD (p = 0.0037).
