Does the Shape of the OGTT Glucose Curve Reflect Metabolic Function in Individuals with Type 2 Diabetes? Baseline Data from the GRADE Cohort

In nondiabetic subjects a biphasic (rise, fall, rise) vs. monophasic (rise then fall) glucose pattern on OGTTs has been associated with better metabolic parameters, but data in T2DM are limited. We categorized the shape of the glucose curve from baseline OGTTs performed in the Glycemia Reduction Approaches in Diabetes Study (GRADE) into monophasic, biphasic or continuous rise and analyzed their relationship with metabolic parameters.
