FGF19 and primary biliary cholangitis: Moreover, the serum levels of FGF19 in noncirrhotic PBC-AIH OS patients were significantly elevated than those in healthy control individuals (771.51 ± 234.97 vs. 255.94 ± 48.54 pg/mL; p = 0.028) and the serum levels of FGF19 in cirrhotic PBC-AIH OS patients were significantly elevated compared to those in either healthy control individuals (2281.25 ± 516.32 vs. 255.94 ± 48.54 pg/mL; p < 0.001) or noncirrhotic PBC-AIH OS patients (2281.25 ± 516.32 vs. 771.51 ± 234.97 pg/mL; p = 0.001) (Table 1) (Figure 1(c)).
