CRP (ng/mL) (A), Hp (µg/mL) (B), ADA (U/mL) (C), TAC (µM/L Trolox equivalents (D), TOS (µM/L peroxidase equivalents) (E), cortisol (µg/dL) (F), Cu (µg/mL) (G), and Zn (µg/mL) (H). Graph showing the distribution of the population, the median (central horizontal line), 25th and 75th percentiles (non-central horizontal lines within the plot), maximum and minimum (edges of the figure). Statistical differences are indicated by *, **, ***, and **** for p < 0.05, p < 0.01, p < 0.001, and p < 0.0001, respectively
