Values expressed as numbers and proportions in parentheses or mean ± SD, as appropriate.

* 24-hours urinary protein excretion ≥ 300 mg/day. eGFR based on MDRD study.

CKD is defined either as kidney damage (proteinuria ≥ 300 mg/day) and/or kidney function (< 60 ml/min/1.73 m2).

Percentages based on total number of dipstick proteinuria available (n = 521).

S. creatinine = serum creatinine; SD, standard deviation.
