Included in the multiple logistic regression analysis; AKI: acute kidney injury; ACEIs: angiotensin-converting enzyme inhibitors; ARBs: angiotensin receptor blockers; CI: confidence interval; OR: odds ratio; VIF: variance inflation factor. value ≤0.05; value ≤0.01. The bold values are significant with one star <0.05, with two stars <0.001.
