A cluster randomized controlled trial for child and parent weight management: children and parents randomized to the intervention group have correlated changes in adiposity

Table 2 Correlations between changes in intervention group children’s (N = 184) and parent’s (N = 184) outcomes from baseline at each study follow-up data collection
