1. Median (interquartile range)
2. Black versus white characteristics for all=P <.001, except died
during study=P <.04
3. Estimated GRF (eGFR) using 4 variable MDRD equation in
ml/min/1.73 m2
4. Protein Group 0: all urinalysis protein results negative
5. Protein Group 1: urinalysis results trace to 1+ protein (30 mg/dL)
6. Protein Group 2: urinalysis results had at least one urinalysis
result >2+ protein (100 mg/dL)
7. Renal function loss (RFL) change in eGFR per year
8. Median (interquartile range) for RFL in ml/min/1.73 m2/years,
calculated as the difference in the average eGFR of the last 12 months
minus the average of the first 12 months, divided by the years of follow
up.
9. Had an eGFR < 30 ml/min/1.73 m2 at some point of the study
10. Had an eGFR <15 ml/min/1.73 m2 at some point in the study |
