Fig. 3From: Evaluation of the national sobriety checkpoints program in Mexico: a difference-in-difference approach with variation in timing of program adoptionDynamic treatment effect (ATT, 95% CI) of sobriety checkpoints on traffic mortality rates.

The not-yet-treated group progressively reduces as more municipalities adopt the program over the yearsBack to article page
