All β values and 95 % confidence intervals in the table are raw data, i.e. data have not been back-transformed.
†
Percentage energy excreted (energy %) (calculated as faecal energy excreted/total energy intake × 100) was square root-transformed and analysed by linear regression model adjusted for age, sex, BMI and supplements containing Ca to investigate the effect of Ca intake (g/10 MJ per d).
‡
Model II + additional adjustment for fibre intake. The interaction fibre × Ca was not significant (P = 0·99) and therefore removed from the model.
