Δ denotes the difference in nutrient intakes between lunch club and non-lunch club days; ß denotes linear regression beta coefficient; CI: Confidence interval; DRV: Dietary reference value; DV/IV: Dependent/independent variables; EI: Energy intake; SFA: Saturated fatty acids.
a Multivariable linear regression models included differences in nutrient intakes as DV and IV were male sex, age (continuous) and being married, and were adjusted for non-lunch club days’ nutrients (continuous).
