Prasanna NS, et al. – This study was undertaken to investigate the oral glucose tolerance test (OGTT) glycemic parameters– fasting, 1hr and 2hr plasma glucose values singly and in various combinations; with respect to their prediction of future dysglycemia in subjects with normal glucose tolerance (NGT). It was concluded that the 1 hour Plasma Glucose value during OGTT is a good predictor of future dysglycemia among NGT subjects.
