Figure 5

Path model of association between iron intake, mtDNAcn, and SOD. In Figure 4, the value for regression (A) was 0.0153, for regression (B) was 0.4453, and for direct effect was 0.0157. As for the indirect effect, significance was achieved when zero was not included in confidence intervals and did not have a value. Models was adjusted for age, hypertension status, BMI, and HbA1c, LnTG, HDL-C, and carbohydrate proportion.
