| Stages of CKD/Heath care (eGFR. ml/min/1.73 m2) |
Primary N = 291 (%) |
Secondary N = 236 (%) |

| 5 (< 15) | 2 (0.7) | 28 (11.9) | 30 (5.7) | < 0.0001 |
| All stages of CKD | 102 (35.3) | 88 (37.4) | 190 (36.2) | 0.68 |
| Proteinuria ≥ 300 mg/day | 52 (17.9) | 47 (19.9) | 99 (18.7) | 0.6 |
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).
