APOA1 and acute kidney injury: African Americans were more likely to develop AKI (12% vs. 26%, p < 0.001) for the HDL group, while females were less likely to develop AKI in both groups (58% vs. 45% with p < 0.001 for the HDL group, and 53% vs. 41% with p = 0.06 for the apoA1 group) although it was statistically significant only at the 10% level for the apoA1 group.
