However, there were no significant differences in median CRP levels across categories of MNA-SF (median CRP levels in malnourished patients: 1.4 (IQR: 0.4–4.3) mg/dl, at risk of malnutrition: 1.4 (IQR: 0.5–4.6) mg/dl and normal nutritional status: 1.1 (IQR: 0.4–4.1) mg/dl). Here, CRP is linked to nutritional deficiency disease.
