Univariate analysis of serious adverse postoperative complications revealed length ofstay ≥5 days (P < .001), wound complications (P =.017), pulmonary complications (P = .019), urinary tract infections(P < .001), intra-/postoperative RBC transfusion (P= .007), sepsis (P = .029), and unplanned readmission (P= .039) were significantly associated with preoperative albumin levels (Table 2). The gene discussed is ALB; the disease is urinary tract infection.
