^aAdjusted for age, gender, smoking dose and alcohol consumption. In addition 'Total meat' and 'Total fruit, berry and vegetable' are mutually adjusted for when assessing their main effect. These variables were not adjusted for when the ratio between them was assessed.

^bQuantities are gram per day. Categories based on quartiles. Numbers vary between the dietary factors due to missing dietary data.
