Risk of progression to dialysis or death on the basis of the kidney failure risk equation for eGFR=30–59 ml/min per 1.73 m2
| eGFR=30–59 ml/min per 1.73 m2 | Risk Group, n (%) | P Value | ||
|---|---|---|---|---|
| Low Risk, n=311 | Medium Risk, n=150 | High Risk, n=68 | ||
| Dialysis (2 yr) | 6 (2%) | <6 (<5%)a | 6 (9%) | 0.02 |
| Death (2 yr) | 40 (13%) | 19 (13%) | <6 (<9%)a | 0.42 |
| Dialysis (5 yr) | 12 (4%) | 16 (11%) | 18 (26%) | <0.001 |
| Death (5 yr) | 96 (31%) | 54 (36%) | 19 (28%) | 0.40 |

Because of the Saskatchewan Health Quality Council privacy rules, small cells (less than six patients) were suppressed. P values correspond to the chi-squared test. Two years indicates risk of CKD progression (to dialysis or death) at 2 years after enrollment; 5 years indicates risk of CKD progression (to dialysis or death) at 5 years after enrollment.
