Comparison of baseline characteristics between the development cohort and the validation cohort
| Variable | All Patients | Development Cohort (CARE FOR HOMe; n=403) | Validation Cohort (n=162) | P Value |
|---|---|---|---|---|
| Age (years) | 60.3±15.3 | 64.6±12.6 | 49.8±16.4 | <0.001 |
| Body weight (kg) | 83.3±17.6 | 86.4±17.5 | 75.7±15.3 | <0.001 |
| Body height (cm) | 169.4±9.4 | 168.9±9.5 | 170.6±9.3 | 0.06 |
| Gender (female) | 235 (41.6%) | 168 (41.7%) | 67 (41.4%) | >0.99 |
| Albuminuria (mg/g creatinine) | 44 (15; 204) | 32 (7; 194) | 57 (32; 318) | 0.61 |
| eGFR (ml/min/1.73 m2) | 55.7±32.7 | 45.8±16.0 | 80.2±47.6 | <0.001 |
| BMI (kg/m2) | 29.0±5.6 | 30.2±5.5 | 26.0±4.5 | <0.001 |
| Systolic BP (mmHg) | 157±25 | 154±23 | 164±26 | <0.001 |
| Diastolic BP (mmHg) | 90±14 | 87±12 | 97±15 | <0.001 |
| Creatinine (mg/dl) | 1.6±0.9 | 1.6±0.6 | 1.7±1.4 | 0.42 |
| RRI | 72±9 | 74±9 | 68±10 | <0.001 |
Depicted are mean±SD, or counts (percentages), as appropriate. Because of skewed distribution, albuminuria is given as median (interquartile range). Conversion factors for units: serum creatinine in mg/dl to mol/L, ×88.4. Information on CARE FOR HOMe is based upon those 403 patients who had baseline renal Duplex ultrasound examinations. BMI, body mass index; RRI, renal resistive index.
