P3H1 and adrenal cortex carcinoma: Kaplan–Meier analysis showed that the high P3H1 expression was linked to poor survival in ACC (OS, DSS, PFI, and DFI), BLCA (OS, DSS, and PFI), KIRC (OS, DSS, and PFI), LGG (OS, DSS, and PFI), LIHC (OS, DSS, PFI, and DFI), MESO (OS, DSS, and PFI), PRAD (PFI and DFI), SARC (OS, DSS, and PFI), and STAD (PFI and DSS), while P3H1 was a protective prognostic factor in THYM (OS) (Figures 4 and 5).
