FGF19 and type 2 diabetes mellitus: Consistent with previous findings, we have shown that HCC patients have significantly lower FPG and TC concentrations than healthy people, and a negative correlation between FGF19 concentration and HbA1c (r = −0.393, p=0.043; not shown in the table) in T2DM patients, consistent with FGF19 improving glucose and lipid metabolism.
