Primary | Odds ratio (OR) for anemia by preoperative anemia status | Multivariable logistic regression will be performed to assess the association between preoperative anemia and postoperative anemia. Several factors will be adjusted: sex, age, BMI, waist circumference, hip circumference, surgery, smoking, alcohol, hypertension, diabetes, hyperuricemia, hypercholesterolemia, and hypertriglyceridemia. | 1 year | |
Secondary | Percentage of postoperative anemia | Percentage of postoperative anemia,, , and low transferrin saturation level. | 1 year | |
Secondary | Percentage of anemia severity | Percentage of anemia severity (mild: hemoglobin=110g/L; moderate: hemoglobin=80g/L; severe: hemoglobin<80g/L). | 1 year | |
Secondary | Percentage of ferritin deficiency | Percentage of ferritin deficiency, which is defined as ferritin less than 30 ng/mL. | 1 year | |
Secondary | Percentage of vitamin B12 deficiency | Percentage of ferritin deficiency, which is defined as vitamin B12 less than 150 pmol/L. | 1 year | |
Secondary | Percentage of folate deficiency | Percentage of folate deficiency, which is defined as folate less than 10 nmol/L. | 1 year | |
Secondary | Percentage of low transferrin saturation level | Percentage of low transferrin saturation level, which is defined as transferrin saturation less than 20%. | 1 year |
