FDX1 and adrenal cortex carcinoma: Consistent with the results of the Cox proportional hazards model of DSS, the K-M curve indicated that high level of FDX1 was positively correlated with good survival outcomes in KIRC (Figure 2G, p = 0.002) and MESO (Figure 2H, p = 0.014), and negatively correlated with survival in ACC (Figure 2F, p = 0.024) and LGG (Supplementary Figure S2E, p < 0.001).
