Contexto
What changed: Implementation of a city ordinance restricting checkout displays within 6 ft of cash registers to healthy foods, beverages, and nonfood items. Comparison: Matched grocery and retail stores in three neighboring California municipalities without the ordinance. Limits: Only two time points evaluated, parallel trends could not be formally verified, and noncompliant items remained widespread further from registers.
