CRP and malnutrition: In the univariate analysis of variables for the CONUT score ≥ 2 (mild or more advanced malnutrition), age (p = 0.0485), BMI (p = 0.020), SARC-F score (p < 0.0001), estimated glomerular filtration rate (eGFR, p = 0.0020), and C reactive protein (CRP, p < 0.0001) were significant factors.
