These ten variables were included in the multivariate analysis, and the results indicated that baseline eGFR (OR = 0.974, 95% CI [0.954–0.994], P = 0.014) and serum albumin (OR = 0.885, 95% CI [0.812–0.964], P = 0.005) levels were negatively correlated with CA-AKI after enhanced CT, while baseline RDW (OR = 2.246, 95% CI [1.616–3.122], P < 0.001) was positively correlated with it (Table 3). Here, ALB is linked to acute kidney injury.
