|---|---|---|---|---|---|---|---|
| Group | Number | Deaths | Person-years | Mortality rate deaths/person-year (95% CI) | Crude MRR (95% CI) | Adjusted MRR a (95% CI) | Adjusted MRR b (95% CI) |
| No AKI | 92,509 | 31,530 | 2.3 x 105 | 0.135 (0.134, 0.137) | 1 | 1 | 1 |
| AKI | 5,273 | 2,943 | 7.6 x 103 | 0.387 (0.374, 0.402) | 2.87 (2.76, 2.97) | 2.14 (2.06, 2.22) | 1.15 (1.09, 1.21) |
aModel 1: adjusted for age, gender, myocardial infarction and diabetes mellitus with complications. bModel 2: adjusted for age, gender, simplified acute physiology score-III, myocardial infarction, cerebrovascular disease, diabetes mellitus with complications, moderate to severe liver disease, cancer and dementia. AKI, acute kidney Injury; MRR, mortality rate ratio.
