  1. Demographic and clinical characteristics among normoglycemia, prediabetes, and diabetes groups are presented in Table 1. Variates are presented as n (%), or median (IQR). The distribution of variables between groups was tested by the Chi-square test or Kruskal-Wallis’s test. A significant association (P < 0.01) is indicated in bold.
