*Stratified by sex, method of recruitment, and region of residence.

†Stratified by sex, method of recruitment, and region of residence and adjusted for smoking, education level, Townsend deprivation index, self reported hyperlipidaemia, receiving long term medical treatment, ever used oral contraceptives, ever used hormone replacement therapy, and BMI (fully adjusted model).

‡χ² test.

§Cut-off points: 14.0, 17.5, 21.2, and 26.1 g/day for men; 14.0, 17.5, 20.9, and 25.5 g/day for women.

¶Further adjusted for sex specific fifths of total energy intake.

**P for trend obtained by replacing fifths of dietary fibre with continuous variable equal to sex specific median in each fifth.
