State gun policies affect veteran and civilian suicide rates differently.
Article in The journal of trauma and acute care surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundVeterans die by suicide with firearms at 1.5 times the rate of civilians. State firearm policies show variable effectiveness, but their differential impact on veteran populations remains unclear. Understanding differential associations is critical given veterans' unique firearm relationships.
methodsAnalysis used state-level data from 2003 to 2022 examining 12 firearm policies across 49 states. Data sources included CDC WISQARS, National Veteran Suicide Prevention Annual Report, and RAND State Firearm Law Database. Mixed-effects models with state random effects and time trends assessed policy impacts on suicide rates. Interaction analyses (Policy × Population) tested differential associations. State-level analysis examined relationships between policy comprehensiveness and veteran-civilian mortality gaps. Bonferroni correction was applied (α=0.00417).
resultsThe analysis included 821 state-year observations from 49 states (2003-2022). Veterans demonstrated higher suicide rates (36.3 per 100,000) compared with the general population (20.1 per 100,000) and greater firearm involvement (67.6% vs. 53.0%). Interaction analysis revealed limited differential policy associations between populations. Only 2 of 12 policies demonstrated differential associations after Bonferroni correction (α=0.00417): local selective preemption showed harmful associations among veterans (+10.11 percentage points, p<0.001), while firearm tracing requirements demonstrated protective associations in the general population (+4.39 percentage points, p=0.001). Geographic disparities in veteran-civilian suicide gaps ranged from 14% (Hawaii) to 162% (Rhode Island). However, no significant correlation was observed between state-level policy comprehensiveness and veteran-civilian gaps (r=.08, 95% CI, -.21 to .35, p=0.583).
conclusionsMost state firearm policies demonstrated similar associations with suicide rates in both populations, and only 2 of 12 policies showed differential associations. The absence of correlation between policy comprehensiveness and veteran-civilian gaps indicates that policy quality and contextual factors matter more than aggregate policy counts. While evidence-based firearm policies benefit both populations, elevated veteran suicide rates persist across all policy environments, indicating that effective prevention requires integration of policy-level interventions with veteran-specific clinical approaches.
