TABLE 1.
Comparison of baseline data of patients with isolated hematuria and non-isolated hematuria.
| Index | Isolated hematuria (n = 29) | Non-isolated hematuria (n = 29) | p-Value |
|---|---|---|---|
| Age at first renal biopsy (Years), mean (S.D.) | 31.0 (10.0) | 35.0 (11.7) | >0.05 |
| Gender (Male/Female) | 9/20 | 13/16 | >0.05 |
| Systolic pressure (mmHg), mean (S.D.) | 125 (15) | 126 (17) | >0.05 |
| Diastolic pressure (mmHg), mean (S.D.) | 79 (10) | 78 (12) | >0.05 |
| Hemoglobin (g/L), mean (S.D.) | 123.6 (17.4) | 127.5 (18.7) | >0.05 |
| Serum creatinine (µmol/L), median (IQR) | 69.0 (51.4–84.2) | 93.0 (73.5–126.8) | <0.05 a |
| GFR (ml/min/1.73 m2), mean (S.D.) | 106.3 (27.3) | 77.9 (31.1) | <0.01 b |
| Uric acid (µmol/L), mean (S.D.) | 317.8 (77.8) | 430.9 (139.9) | <0.05 a |
| Albumin (g/L), mean (S.D.) | 40.8 (5.8) | 32.9 (8.9) | <0.01 b |
| Triglyceride (mmol/L), median (IQR) | 1.1 (0.8–1.3) | 1.7 (1.1–2.8) | <0.05 a |
| Urine protein (g/d), median (IQR) | 0.3 (0.2–0.4) | 2.6 (2.1–4.2) | <0.05 a |
| Hematuria (RBC/ul), median (IQR) | 30 (4–35) | 20 (10–30) | >0.05 |
Note: GFR, glomerular filtration rate. Continuous variables were expressed as mean ± S.D., if normal distribution, as median (interquartile range) if non-normal distribution. Categorical variables were expressed as counts. Comparisons were based on Wilcoxon rank-sum test, t-test, or chi-square test.
a
represented that P was less than 0.05.
b
represented that P was less than 0.01.
