After adjustment for age and gender, the DM-CR group had a significantly higher FGF 19 level compared to DM-non-CR at M3 (196.88 ± 153.00 vs. 102.06 ± 34.72 pg/mL, p = 0.004, shown in Figure 3B), and more changes in FGF 19 between M3 and M0 (133.15 ± 144.65 vs. 6.15 ± 86.35 pg/mL, p = 0.001, shown in Figure 3D) compared with the DM-non-CR group. The gene discussed is FGF19; the disease is diabetes mellitus.
