Exploratory analysis of change in fasting glucose a. Change in levels of mean fasting glucose when stratified by age at baseline. At baseline, the mean ages of grouped subjects were approximately 16 years for G1, 27 years for G2, and 43 years for G3, respectively. The mean of the fasting glucose levels over the five time points was 91.33 mg/dl in G1, 93.82 mg/dl in G2, and 102.06 mg/dl in G3, respectively. b. Change in mean fasting glucose levels stratified by initial levels.Fasting glucose levels were grouped at baseline as <100 mg/dl, 100–125 mg/dl, ≥ 126 mg/dl, and followed over all five time points.
