In the case of hemoglobin, we observed a positive correlation between the concentration of Hb and the concentration of FGF19 24 h after transplantation in HCC patients (r = 0.4889, p = 0.033) and 2 weeks after transplantation in HBV patients (r = 0.6997, p = 0.011). The gene discussed is GSTM1; the disease is hepatocellular carcinoma.
