Directed Acyclic Graph mapping hypothesised confounders and moderators of the relationship between parental FV intake and adolescent FV intake. Note: Parental FV intake (exposure) is hypothesised to be associated with adolescent FV intake (outcome). This association could be confounded by geographic region, ethnicity, parental education and household income, all of which potentially have causal associations with the exposure or the outcome. Adolescent FV intake could differ by sex, a competing exposure. Age of adolescent and living with parents are hypothesised moderators of the relationship between parental FV intake and adolescent FV intake. Created in www.dagitty.net
