Patients with low hemoglobin or hepcidin are more likely to have anemia (mostly iron defiency anemia) with p value of 0.008 for hemoglobin and < 0.001 for hepcidin while patients with high level ferritin and CRP are more likely to have anemia (anemia of chronic disease) with p value of < 0.0001 for ferritin and CRP. The gene discussed is CRP; the disease is anemia.
