<p>Data are <i>n</i> (%) or median (interquartile range) for continuous variables. For categorical descriptors, values are counts (percentage of total for that cohort). Differences in frequency between converters and nonconverters were evaluated with a Monte Carlo estimation of the χ² statistic (2,000 replicates). Differences in medians of continuous variables were evaluated with a Wilcoxon test. NFG, normal fasting glucose; IFG, impaired fasting glucose; eHbA1c, elevated hemoglobin HbA1c.
