Potential Protective Effect of Dietary Intake of Non-α-Tocopherols on Cellular Aging Markers Mediated by Tumor Necrosis Factor-α in Prediabetes: A Cross-Sectional Study of Chinese Adults

Figure 3

Mediation model of association among (a) δ-Toc, TNF-α, and mtDNAcn; (b) β-/γ-Toc, TNF-α, and mtDNAcn; (c) δ-Toc, TNF-α, and LTL; (d) β-/γ-Toc, TNF-α, and LTL; (e) δ-Toc, HbA1c, and LTL; and (f) β-/γ-Toc, HbA1c, and LTL in prediabetic individuals. Zero that is not included in the 95% CI represents statistical significance. Abbreviations: Toc—tocopherol(s); LTL—leukocyte telomere length; mtDNAcn—mitochondrial DNA copy number; TNF-α—tumor necrosis factor-α; HbA1c—glycosylated hemoglobin.
