Multivariable logistic regression analysis indicated that male sex (odds ratio [OR], 4.45; 95% confidence interval [CI], 1.80–11.82; P = 0.002), preoperative use of beta-blockers (OR, 4.81; CI, 1.24–16.50; P = 0.016), low preoperative serum albumin levels (OR, 0.29; 95% CI, 0.11–0.76; P = 0.011), and colloid administration (OR, 5.18; 95% CI, 1.42–18.15; P = 0.011) were associated with the occurrence of postoperative AKI (Table 3). The gene discussed is ALB; the disease is acute kidney injury.
