AUC for the RIFLE, AKIN, and KDIGO definitions to predict hospital mortality
| Criteria | AUC | P Value | ||
|---|---|---|---|---|
| All patients (n=49,518) | ||||
| RIFLE | 0.77 | <0.001 | ||
| AKIN | 0.69 | <0.001 | ||
| KDIGO | 0.78 | 0.02 | ||
| Patients with baseline creatinine measured at outpatient clinic (n=30,188) | ||||
| RIFLE | 0.76 | <0.001 | ||
| AKIN | 0.67 | <0.001 | ||
| KDIGO | 0.77 | 0.15 | ||
| Patients with baseline creatinine estimated by MDRD equation (n=19,330) | ||||
| RIFLE | 0.82 | <0.001 | 0.07 | |
| AKIN | 0.73 | <0.001 | <0.001 | 0.07 |
| KDIGO | 0.82 | <0.001 | 0.07 | |
P value <0.02 was considered to be statistically significant. AUC, area under the receiver operating characteristic curve; MDRD, Modification of Diet in Renal Disease.
