  • Data are % ± SEM or mean ± SEM. Adults with prediabetes included those with IGT (2-h glucose concentration 140–199 mg/dl) and/or IFG (fasting glucose concentration 110–125 mg/dl) (12). Also included in analysis were people meeting DPP criteria for IGT (9). See research design and methods for details.
