Statistics details: one-way ANOVA for ApoC2, ApoC3, ApoE, and ApoH; Kruskal-Wallis test for TC, TG, HDL-C, LDL-C, LPO, POD, SOD, CAT, GSH-px, IL-1β, IL-4, IL-6, IL-10, TNF-α, TGF-β, RANTES, ApoA1, ApoA2, ApoB, and ApoJ.
Data of ApoA2, ApoC3, ApoE, and ApoH are presented as mean ± SD; data of TC, TG, HDL-C, LDL-C, LPO, POD, SOD, CAT, GSH-px, IL-1β, IL-4, IL-6, IL-10, TNF-α, TGF-β, RANTES, ApoA1, ApoA2, ApoB, and ApoJ are presented as median (first quartile–third quartile).
Compared to 24 ≤ MMSE ≤ 27, .
Borderline significance.
As the objective concentration was too low, the fluorescence intensity was used as the relative concentration.
