Mediation results from models in which daily time spent within 50 m of tobacco outlet was modeled as the exposure (a) and daily time spent within 100 m of tobacco outlet polylines was modeled as the exposure (b). In panel a, the Akaike information criterion value was 2393.64 and the Bayesian information criterion value was 2520.24. The indirect effect through exposure to peers who use tobacco was not significant at p = .66. The indirect effect through exposure to adults who use tobacco was not significant at p = .74. In panel b, the Akaike information criterion value was 2382.69 and the Bayesian information criterion value was 2508.96. The indirect effect through exposure to peers who use tobacco was not significant at p = .41. The indirect effect through exposure to adults who use tobacco was not significant at p = .90.
