  1. Abbreviations: BP, blood pressure; eGFR, estimated glomerular filtration rate; HDL, high-density lipoprotein cholesterol; LDL, low-density lipoprotein cholesterol; UAE, urinary albumin excretion.
  2. Data are expressed as mean±s.d. or median (interquartile range) for continuous variables and as percentage for categorical variables.
  3. eGFR Quartiles 1, 2, 3 and 4 indicate 90–169, 77–89, 72–76 and 40–71 ml min−1 per 1.73 m2, respectively.
  4. P-values indicate the results by analysis of variance or chi square test. The bold values indicate statistically significant components.
