DPP4 and Insulin resistance: Among the baseline clinical variables depicted in table 1, baseline DPP4 activity correlated with the hepatic markers alanine aminotransferase (ALAT) (rho=0.274, p=0.026) and gamma-glutamyltransferase (GGT) (rho=0.280, p=0.002) while there were no significant correlations with BMI (rho=0.082, p=0.508) or the marker of insulin resistance HOMA-IR (rho=0.172, p=0.175).
