  1. * Data were analysed by a linear mixed model for repeated measures. Fixed effects were intervention condition, gender, class level, and time (survey). Random effects were added for pupil and school, where pupils were nested within schools. Interaction effects included in the models: time and intervention condition (all models), sex and intervention condition (FV all day, usual FV intake), time and sex (FV at school, soda/candy/chips).
  2. ** Numbers in the parenthesis are adjusted for individual subscription to the school fruit programme. For usual FV intake an interaction between individual subscription and intervention was included.
