Logistic regression analysis using model 3 (Table 4) showed that age ≥65 years, female sex, albumin level ≤3.5 g/dl, difference between sodium and chloride concentrations (Na–Cl) ≤30 mEq/L, and CRP level ≥0.3 mg/dl were also independent risk factors for increased prevalence of anemia (JSDT2 Criteria). Here, CRP is linked to anemia (phenotype).
