FTH1 and cancer: FTH1 expression was significantly associated with PFI in eight cancer types (Figure 3D): PRAD (HR 1.89, 95% CI 1.21–2.95, P = 5.5 × 10−3), KIRP (HR 1.83, 95% CI 1.29–2.6, P = 6.9 × 10−4), CESC (HR 1.5, 95% CI 1.13–1.99, P = 5.3 × 10−3), HNSC (HR 1.35, 95% CI 1.13–1.6, P = 6.9 × 10−4), LGG (HR 1.67, 95% CI 1.26–2.21, P = 3.4 × 10−4), DLBC (HR 0.47, 95% CI 0.24–0.92, P = 2.7 × 10−2), KICH (HR 5, 95% CI 1.55–16.19, P = 7.2 × 10−3), and UVM (HR 2.97, 95% CI 1.23–7.16, P = 1.6 × 10−2).
