Table 1 Binary logistic regression model showing the association of independent associations of serum folate level, hemoglobin level, vitamin B12 level, age, ferritin level, and sex with the presence of RBC macrocytosis (MCV >100)

From: Folate deficiency in an unselected population in Calgary, Alberta and its relationship with red blood cell macrocytosis

Variable P value OR (95% CI)
Serum folate level <0.001 0.990 (0.986–0.984)
Hemoglobin level 0.141 0.999 (0.999–1.004)
Vitamin B12 level <0.001 1.000 (1.000–1.001)
Age <0.001 1.023 (1.021–1.026)
Serum ferritin level <0.001 1.001 (1.001–1.001)
Sex (female) 0.004 0.788 (0.788–0.957)
