value="Participants whom provided blood specimen but did not meet the 8 to less than 24 hour fasting criteria (n=180) have the sample weight value assigned as '0' (WTSAF2YR =0) as well. Glucose measurements for these 180 participants are included in the dataset. However, to include these data in the analysis, a reweighting would be required."/>
