The predictive model was established as: Ln (P/1−P) = −2.230 + 1.467 * diabetes + 0.117 * preoperative white blood cell count −0.146 * preoperative albumin + 0.001 * intraoperative blood transfusion + 0.864 * drainage tube indwelling + 0.003 * drainage volume + 0.656 * ventilator use time + 0.103 * central venous catheterization time. Here, ALB is linked to diabetes mellitus.
