Multivariate linear regression analyses of the energy-adjusted DTAC and serum biomarkers of oxidative stress (n = 175)

DTAC (μmol/day)†	Coefficient standard β	P-value
TAC (mM)	0.006	0.9
MDA (µM)	− 0.37	< 0.001
Ox-LDL (ng/l)	− 0.04	0.5
SOD (U/ml)	− 0.13	0.07

Adjusted for age (year) and years since menopause (year) education (year), waist circumference (cm), physical activity (MET min/week), dietary supplement use (yes/no), dietary intake of fiber (g/day), energy (kcal/day) and coffee (g/day)

Serum biomarkers of oxidative stress were log10 transformed

DTAC dietary total antioxidant capacity, TAC total antioxidant capacity, MDA malondialdehyde, Ox-LDL oxidized low-density lipoprotein, SOD superoxide dismutase

^†DTAC was adjusted for energy intake by residual method
