| Model 1a | 0.93 (0.85, 1.02) | 0.84 (0.67, 1.06) |

Values are HR and 95% CI obtained from Cox proportional hazards models according to each 2 g/day and 5 g/day increase in total, soluble and insoluble fibre. Fibre intake was adjusted for total energy intake (kJ/day) using the nutrient residual method [31]
aModel 1 adjusted for age (continuous), sex and energy (kJ/day)
bModel 2 additionally adjusted for diabetes duration (years), HbA1c (%), smoking status (no, previous, current), physical activity (physical inactivity, mild physical activity ≥1 time/week, moderate physical activity ≥1 time/week, vigorous physical activity ≥1 time/week) and alcohol intake (0, >0–<5, 5–<15, 15–<30, 30–<40, ≥40 g/day)
cModel 3 additionally adjusted for SFA intake (en%)
