After controlling for preoperative functional health status, history of CHF, history of a bleeding disorder, mFI-5, ASA, preoperative albumin level, preoperative HCT level, preoperative WCC, and perioperative transfusion, unplanned surgery was found to be significantly associated with FTR (OR 2.11 [95% CI 1.24 to 3.56]; p = 0.005) in our multivariable model (Table 2). This evidence concerns the gene ALB and hemorrhagic disease.
