In total, 3,515 pairs of consecutive OGTTs are summarized. For each pair, the first test was categorized in one of the five glucose tolerance classes (NGT, IFG only, IGT only, IFG+IGT, DGT). The figure shows the percentage of subsequent test results for each glucose tolerance category. The number in parentheses indicates the number of OGTTs available for analysis. Abbreviations: NGT normal glucose tolerance, IFG impaired fasting glucose, IGT impaired glucose tolerance, DGT diabetic glucose tolerance, OGTT oral glucose tolerance test.
