Model 1 (Non-adjusted model): not adjust any covariate
Model 2 (Minimally-adjusted model): only adjusted age, sex and race
Model 3 (fully-adjusted model): adjusted age, sex, race, anesthesia type, Revised Cardiac Risk Index (RCRI) score, Transfusion Intra and postop Category, preop-transfusion within 30 days, anesthesia type, priority of surgery, surgical risk, and RDW
