%E, percentage of total daily energy intake.

Model I: adjusted for age and gender.

Model II: adjusted for age, gender, education, smoking, physical activity and intakes of total fat, total carbohydrates, total fibre, and fruit and vegetables.

Model IIIa: adjusted for covariates in model II and total vegetal protein (%E).

Model IIIb: adjusted for covariates in model II, total vegetal protein (%E) and protein from other animal sources (%E).
