Serum and urine betatrophin concentrations of healthy and T2DM patients with normoalbuminuria, microalbuminuria and macroalbuminuria. a Serum full-length betatrophin level was measured by N-terminal kit and b serum total betatrophin level was measured by C-terminal kit. c Correlations between N-terminal kit and C-terminal kit. d Urinary betatrophin level was measured by N-terminal kit. Data are mean ± SEM. *P < 0.05 vs. healthy subjects; ^†P < 0.05 vs. normoalbuminuria; ^‡P < 0.05 vs. microalbuminuria
