Table 4 Final Mediation Model–direct and mediated effects of treatment (group allocation) and each mediator on 12-month outcome (child fruit and vegetable consumption score)

From: Characteristics of the home food environment that mediate immediate and sustained increases in child fruit and vegetable consumption: mediation analysis from the Healthy Habits cluster randomised controlled trial

Standardised effects of treatment & mediators on 12-month outcome (child fruit and vegetable consumption score) (se)

  2. athis is the effect of group allocation on the 12 months F&V consumption that is mediated through parent provision and intake at 2 and 12 months, and F&V consumption at 2 months
  3. bthis is the effect of parent provision at 2 months on 12 months F&V consumption that is mediated through parent provision at 12 months and F&V consumption at 2 months
  4. cthis is the effect of parent intake at 2 months on 12 months F&V consumption that is mediated through parent intake at 12 months and F&V consumption at 2 months
