CISD1 and liver cancer: The results showed that higher CISD1 mRNA expression was correlated with the poor prognosis in liver cancer (OS HR = 1.5 (1.06−2.12), p = 0.021; PFS HR = 1.32 (0.98−1.78), p = 0.071; RFS HR = 1.46 (1.04−2.03), p = 0.026; and DSS HR = 1.51 (0.97−2.35), p = 0.068) (Figures 3(a)–3(d)).
