Individuals with obesity exhibited associations with various perioperative parameters, e.g., diminished levels of alkaline phosphatase (AP) (p = 0.019) and platelet count (p = 0.048), lower pT category (p = 0.018), lower prothrombin time (p = 0.025), and shorter hospitalization (p = 0.003) as well as higher hemoglobin (p = 0.001) and albumin levels (p = 0.032). This evidence concerns the gene F2 and Obesity.
