INS and type 2 diabetes mellitus: Subjects with NGT (normal glycemia according to both fasting and 2- h glucose) (n=17) differed from IGT and/or T2D (IGT+T2D: n=10) only in glucose area under the curve (NGT: 867±160 mgmindl−1, IGT+T2D: 1082±133.4 mgmindl−1; P<0.01) and fasting plasma insulin (NGT: 29±18.9 μU ml−1, IGT+T2D: 46.5±25.6 μU ml−1; P<0.05) (Supplementary Table).
