Characteristics of the Colaus sample.

BMI = body mass index; GFR = glomerular filtration rate (calculated according to Modification in Diet in Renal Disease equation); IL-1β = interleukin-1β; IL-6 = interleukin-6: TNF-α = tumour necrosis factor-alpha; CRP = ultrasensitive C-reactive protein.Results are presented as mean (SD), percentages or median (interquartile range) for those marked with an asterix. Between-group comparisons by ttest, Chi-square test or Wilcoxon ranksum test.身体质量指数（body mass index, BMI）；肾小球滤过率（glomerular filtration rate, GFR，根据肾脏病饮食改良（Modification in Diet in Renal Disease, MDRD）方程计算）；白细胞介素-1β（interleukin-1β, IL-1β）；白细胞介素-6（interleukin-6, IL-6）；肿瘤坏死因子-α（tumour necrosis factor-alpha, TNF-α）；超敏C反应蛋白（ultrasensitive C-reactive protein, CRP）。带星号标记的结果以均值（标准差，SD）、百分比或中位数（四分位数间距）形式呈现。组间比较采用t检验、卡方检验或Wilcoxon秩和检验。
