Demographic characteristics and laboratory measurements, by AKI cause
| Variable | AKI-ICI (N = 14) | AKI-Other (N = 10) | Total (N = 24) | P-value |
|---|---|---|---|---|
| Age (yr), mean (SD) | 65.4(14.6) | 62.4(14.2) | 64.1(14.2) | 0.63 |
| Gender | 0.63 | |||
| Male | 7(50.0%) | 6(60.0%) | 13(54.2%) | |
| Female | 7(50.0%) | 4(40.0%) | 11(45.8%) | |
| White race, n (%) | 14(100.0%) | 10(100.0%) | 24(100.0%) | - |
| Serum creatinine, median (IQR) | 1.9 (1.7,2.4) | 1.7 (1.5, 3.5) | 1.8 (1.6, 2.6) | 0.62 |
| eGFR (CKD-EPI), mean (SD) | 29.9(10.8) | 34.0(17.9) | 31.6(14.0) | 0.49 |
AKI, acute kidney injury; CKD-EPI, chronic kidney disease-epidemiology collaboration equation; eGFR, estimated glomerular filtration rate; ICI, immune checkpoint inhibitors; IQR, interquartile range.
P-values are derived from the equal variance t-test for normally distributed variables, the Wilcoxon rank sum test for non-normally distributed variables, the χ2 test for categorical variables where the expected call counts were ≥5, and the Fisher exact test for categorical variables with an expected cell count of <5.
