Regarding PFS (Figure 3B), a high expression of FDX1 was associated with poor PFS in LGG (HR = 2.74, p = 0.001) and ACC (HR = 1.34, p = 0.005), while a high expression of FDX1 could predict favorable PFS in mesothelioma (MESO) (HR = 0.54, p = 0.028), KIRC (HR = 0.49, p = 0.001), and THCA (HR = 0.46, p = 0.001). The gene discussed is FDX1; the disease is mesothelioma.
