DAG demonstrating the relationship among contemporaneous greenness, perceived stress and their mediators, confounders, and effect modifiers. Pathway a represents of the direct, unmediated, association between greenness and perceived stress. Pathway b demonstrates the role of mediators, in which greenness has an indirect effect of which respiratory disease history and physical activity are on the causal pathway. Pathway c shows the effect modifiers that modify the greenness’ effect on the perceived stress. Pathway d depicts the presence of confounders because they predict both the greenness and stress
