Figure A2.

Odds ratios from logistic regression models with restricted cubic spline curves describing the association between baseline consumption of (a) total DF, (b) total RS, (c) DF from discretionary foods, (d) DF from other foods, (e) RS discretionary foods, (f) RS from other foods, in g/d with 5 year MCS scores (vertical axis) in 4067 Australian adults from the AusDiab study (excludes those with baseline MCS score < 47). Odds ratios are based on models adjusting for age, sex, BMI, energy intake, relationship status, physical activity, level of education, the socio-economic index for areas (SEIFA), smoking status, diabetes status, and self-reported history of CVD, and are comparing the specific level of intake (horizontal axis) to the median (IQR) intake for participants in the lowest intake quartile of total DF: 13 g/day; total RS: 6 g/day; DF from discretionary foods: 0.8 g/day); DF from other foods: 5 g/day; RS from discretionary foods 0.3 g/day; RS from other foods: 1.8 g/day. DF, dietary fibre; MCS, SF 36 Quality of Life Scale mental component summary scores (Australian norm-based); RS, resistant starch.
