Baseline characteristics, stratified by IGR status and the EZSCAN value.

Values are mean ± SD, n (%), or median (interquartile range). Normal variables were compared using the Student t test, and non-normal variables were logistically transformed and compared using the Student t test. Categorical variables were compared using the chi-square test.NGT, normal glucose tolerance; IGR, impaired glucose regulation; CVD, cardiovascular disease; HDL cholesterol, high-density lipoprotein cholesterol; GFR, glomerular filtration rate.*P†P数据以均值±标准差（Standard Deviation, SD）、例数（百分比）或中位数（四分位数间距）的形式呈现。正态分布变量采用学生t检验进行组间比较，非正态分布变量经对数变换后采用学生t检验进行比较。分类变量采用卡方检验进行组间比较。正常糖耐量（normal glucose tolerance, NGT）、糖调节受损（impaired glucose regulation, IGR）、心血管疾病（cardiovascular disease, CVD）、高密度脂蛋白胆固醇（high-density lipoprotein cholesterol, HDL-C）、肾小球滤过率（glomerular filtration rate, GFR）。*P†P
