the average concentrations of FGF21 during 7 hours in T2DM and NC were 130.57±37.51 ng/L and 115.7±30.54 ng/L, respectively (P = 0.054).The AUCs of FGF21 did not differ significantly between the 2 groups (T2DM: 949.4±471.47 ng/L; NC: 883.13±561.40 ng/L, P = 0.77) (Table 2). Here, FGF21 is linked to type 2 diabetes mellitus.
