ALB and neoplasm: Multivariate Logistic regression analysis identified age (p = 0.017, OR = 1.041, 95% CI: 1.007-1.076), preoperative albumin level (p < 0.001, OR = 0.774, 95% CI: 0.704-0.851), tumor location (p = 0.012, OR = 2.243, 95% CI: 1.216-4.906), and operation duration (p < 0.001, OR = 1.007, 95% CI: 1.003-1.011) as independent risk factors for moderate-to-severe complications after PTR surgery.
