  1. Values expressed as numbers and proportions in parentheses or mean ± SD, as appropriate.
  2. * 24-hours urinary protein excretion ≥ 300 mg/day. eGFR based on MDRD study.
  3. CKD is defined either as kidney damage (proteinuria ≥ 300 mg/day) and/or kidney function (< 60 ml/min/1.73 m2).
  4. Percentages based on total number of dipstick proteinuria available (n = 521).
  5. S. creatinine = serum creatinine; SD, standard deviation.
