Values are multivariate adjusted means (95% CIs)
*Significant differences between means across red meat (RM) tertiles were determined by ANCOVA controlling for age, energy intake, socioeconomic classification (SEC) and number of daily cigarettes (Base model), with additional adjustment for BMI (+ BMI) and further adjustment for fruit and vegetables, fibre, dairy, oily fish and nuts (+ dietary factors). For height and weight model 3 did not include adjustment for BMI. Tertiles that do not share a superscripts letter were significantly different at P<0.05 based on Bonferroni post hoc pairwise comparisons
