GPX4 and hereditary elliptocytosis: As shown in Table 5, the TBIL level (HR = 1.004, 95%CI: 1.002–1.007), WBC count (HR = 1.121, 95%CI: 1.009–1.246), PTA (HR = 0.910, 95%CI: 0.875–0.946), INR (HR = 3.465, 95%CI: 2.124–5.652), HE (HR = 3.419, 95%CI: 1.627–7.182), MELD score (HR = 1.217, 95%CI: 1.141–1.299) and GPX4 PMR (HR = 1.050, 95%CI: 1.034–1.067) were significantly correlated with 90-day mortality in HBV-ACLF patients.
