Figure 4. Relationship between the disulfidptosis score and pan-cancer overall survival (OS), disease-specific survival (DSS), disease-free interval (DFI), and progression-free interval (PFI). Univariate Cox proportional hazard regression analysis between the disulfidptosis score and pan-cancer OS (A), DSS (B), DFI (C), and PFI (D). The abscissa represents the log2 (HR) value. A high-risk factor for cancer with a poor prognosis is one with a hazard ratio > 1. A hazard ratio of <1 is considered to be low-risk for cancer in comparison.
