Mass shootings durably increase the sale of alcohol in American communities.
Article in PNAS nexus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Mass shootings are devastating events. Communities can cope with the ensuing trauma in a number of ways, including changing their behavioral patterns. Using point-of-sale data from 35,000 individual retailers, including more than half of all American grocery and drugstore purchases, and all American mass shootings from 2006 to 2019, we find, in a set of two-way fixed-effects counterfactual analyses, that a mass shooting in a given community (the area covered by the ZIP-3 code) predicts a significant increase in the sales of alcohol that lasts at least 2 years past the shooting. The effect is especially strong for the subset of mass shootings that take place in public settings, whereas we find no evidence for an increase in alcohol sales in the aftermath of mass shootings that take place in private homes or residences. As alcohol is an accelerant for violence, especially firearm-related violence, we suggest the importance of whole-community approaches to addressing the trauma of mass shootings.
