Glomerular cause of ESRD ^ | 0.31 | 0.05 | 0.95 – 1.0 |
Diabetes as cause of ESRD ^ | 0.57 | 0.24 | 0.23 – 1.4 |
Percentage calculations are based on patients in whom the variable of interest was known.
The joint test of glomerular disease and diabetes as cause of ESRD relative to other causes as a predictor of initial modality yielded a p = 0.13
Data are presented as mean ± standard deviation if normal, and as median, 25th percentile – 75th percentile if not.
