Estimates are given as the mean (SD) or number (percent). There were 11 missing values hemoblobin A1C, one for diabetes, five for current smoking, and six for albuminuria.
a
Numbers are undiagnosed diabetes on the basis of fasting glucose or hemoglobin A1c. Those with self-reported diabetes were excluded at baseline.
b
ACR>30 mg/g.
c
GFR measured using single-sample iohexol clearance. GFR was not measured at baseline for the additional 210 persons included in RENIS-3 who did not attend RENIS-T6.
