Efficacy
Statistical methods / analysis
Retrospective target sample size calculation: 60 per group required to achieve a medium effect size with power of 80 (Cohen) - total 120 + 30% drop out = 160. All children attending the participating schools were invited to take part so there was no upper limit. Data were analysed using linear mixed modelling.
