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

Percentages based on responding number or total participant number. For three patients, the sample of serum was not properly handled (missing data).

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

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