Abbreviations: BMI, body mass index; FBS, fasting blood sugar; HbA1c, glycosylated hemoglobin; sUA, serum uric acid; Cr, creatinine.
aeGFR (estimated glomerular filtration rate) calculated from the results of blood creatinine, age, body size and gender.
b GFR (MDRD), calculated from the Modification of Diet in Renal Disease (MDRD) equation. Data for categorical variables are presented as percentages.
cParametric and non-parametric variables were extracted as mean ± SD and median, quartile respectively.
