Univariate logistic analysis showed that baseline eGFR, anemia, baseline albumin (Alb) < 30 g/L, and use of ACEIs/ARBs, antibiotics, diuretics, NSAIDs, PPIs, nivolumab, toripalimab, sintilimab and extrarenal irAEs were associated with the occurrence of AKI (P < 0.05). This evidence concerns the gene ALB and anemia.
