Fig. 2: Cognitive functions between plasma VA levels.

a Cognitive function across the quintiles of plasma VA levels. b Cognitive function across the quintiles of plasma VA/(TC + TG) levels. General linear model was applied to compare the cognitive functions between groups, adjusting age, gender, BMI, education, physical activity, living alone, reading habits, using TV and computer, smoking, drinking alcohol, usage of dietary supplements, AD family history, hyperlipidemia (not adjusted if compared between quintiles of plasma VA/(TC + TG) levels), stroke, chronic kidney disease, T2DM, LBS, and HBS.
