Table 2. Characteristics of patients with IgAN and CKD controls.
| IgAN patients | CKD controls | Healthy controls | |
| Numbers | 135 | 79 | 106 |
| Age (years) | 34.6±11.9 | 50.9±19.4 | 32.6±5.2 |
| Sex (male/female) | 56/79 | 42/37 | 61/45 |
| Serum creatinine (mg/dl) | 0.93±0.53 | 2.26±2.52 | ND |
| eGFR (ml/min/1.73 m2) | 76.9±25.8 | 55.7±39.2 | ND |
| Urine P/C (g/g) | 0.65±0.84 | 3.01±3.19 | ND |
| Hematuria | 4.08±2.28 | 1.60±2.23 | ND |
Values are mean ±SD.
eGFR, estimated glomerular filtration rate; P/C, protein/creatinine ratio; ND, not determined.
Hematuria: Assessed by assigning scores according to number of red blood cells per high-power field (RBC/HPF).
≤5 RBC/HPF = 0, 6–10 RBC/HPF = 1, 11–15 RBC/HPF = 2, 16–20 RBC/HPF = 3, 21–25 RBC/HPF = 4, 26–30 RBC/HPF = 5, >30 RBC/HPF = 6.
