<qa>  What is the significance of p0.05?Continuous variables will be described by univariate summaries; frequency distributions will be determined for categorical variables. Participant characteristics e.g., weight status, child sex will be examined to assess equivalence of intervention groups at baseline, and attrition tendencies across sub-groups will be examined using two-way ANOVA. Multilevel modelling will be used to assess intra- and inter-level individual and group change in the primary and secondary outcomes; this form of analysis is appropriate when observations are nested within groups andor multiple time points. Estimates of effect sizes will be based on percent change in primary outcomes. Significance will be p0.05.
