Bold results are statistically significant at the 0.05 level.
aExact cutpoints are 0–3.75 (low), 4–7.8 (intermediate), and 8–30.7 (high) for mean tobacco retailer counts in the activity space, and 0–1 (low), 2–5 (intermediate), and 6–45 (high) for tobacco retailer counts in the residential neighborhood.
