Multivariablea linear regression analysis of index visit values of eGFR on urine protein-to-creatinine (milligrams per milligram) and urine albumin-to-creatinine (milligrams per gram), n=647
| Exposureb | No. | Mean eGFR (millilitre per minute per 1.73 m2) Relative to Reference | 95% Confidence Interval |
|---|---|---|---|
| Urine protein-to-creatinine <0.2 and urine albumin-to-creatinine <30 | 170 | 0 (reference) | |
| Urine protein-to-creatinine <0.2 and urine albumin-to-creatinine ≥30 | 86 | −3.1 | −8.1 to 1.9 |
| Urine protein-to-creatinine ≥0.2 and urine albumin-to-creatinine <30 | 21 | −9.3 | −17.8 to −0.7 |
| Urine protein-to-creatinine ≥0.2 and urine albumin-to-creatinine ≥30 | 370 | −16.0 | −19.7 to −12.4 |
a
Adjusted for age, sex, race, CKD cause, hypertension status, body mass index, and uric acid.
b
For urine protein-to-creatinine the units are mg/mg; for urine albumin-to-creatinine the units are mg/g.
