^aPolicy scores were standardized to US national distribution. Higher scores indicated weaker policies.

^bF-tests had 4 and 18 degrees of freedom for the numerator and denominator, respectively.

^cModel controlled for alcohol provider policy score.

^dModel controlled for underage youth policy score.

^eModel controlled for neighborhood (median age, socioeconomic disadvantage) and individual factors (sex, race/ethnicity, family affluence).s
