Mediation results from models in which daily exposure to number tobacco outlets within 50 m of polylines was modeled as the exposure (a) and daily exposure to number of tobacco outlets within 100 m of polylines was modeled as the exposure (b). In panel a, the Akaike information criterion value was 2358.47 and the Bayesian information criterion value was 2484.73. The indirect effect through exposure to peers who use tobacco was significant at p = .001. The indirect effect through exposure to adults who use tobacco was not significant at p = .78. In panel b, the Akaike information criterion value was 2356.07 and the Bayesian information criterion value was 2482.34. Indirect effect through exposure to peers who use tobacco was significant at p = .001. The indirect effect through exposure to adults who use tobacco was not significant at p = .73.
