State laws addressing teen dating violence in US high schools: A difference-in-differences study.
Article in Preventive medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTeen dating violence (TDV) is prevalent with lifelong adverse consequences, and strategies to reduce its burden are needed. Many U.S. states have enacted laws to address TDV in schools, but few studies have examined their effectiveness. This study aimed to assess whether state TDV laws were associated with changes in physical TDV victimization among high school students.
methodsWe used repeated cross-sectional data of high school students from the Youth Risk Behavior Survey across 41 states from 1999 to 2019. Using a difference-in-differences approach with an event study design, we compared changes in past-year physical TDV in states that enacted TDV laws (n = 21) compared to states with no required laws (n = 20). Analyses accounted for clustering at the state-level and state and year-fixed effects. We conducted sensitivity analyses to assess the robustness of our findings.
resultsIn our sample of 1,240,211 students, the prevalence of past-year physical TDV was 9.2% across all state-years. In 1999, the prevalence of TDV at the state-level ranged from 7.5 to 13.0%; in 2019, the prevalence ranged from 3.7 to 10.5%. There was no significant association between TDV laws and past-year physical TDV. Six or more waves after enactment, we observed a non-significant 1.7% percentage point reduction in TDV in states with TDV laws (95% CI: -3.6 to 0.3 percentage points; p = 0.10).
conclusionsWe found no significant association between enactment of TDV laws and physical TDV among high school students. Further research is needed to understand how TDV laws are implemented and components of TDV laws that may influence effectiveness.
