Non-parametric test was adopted with t-statistics;
CI – cognitive impairment; BMI – Body Mass Index; TSF – triceps skin fold; LDL-C – low density lipoprotein cholesterol; IgA – immunoglobulin A; IgG – immunoglobulin G; IgM – immunoglobulin M; NK cell – natural killer cell; B cell – bursa dependent lymphocyte; ADL – activities of daily living; GDS – global deterioration scale; MNA – mini nutritional assessment; PG-SGA – patient-generated subjective global assessment.
