Evaluation of a Region-Wide Hospital-Based Violence Intervention Program : A Pilot Cohort Study.
Observational study in Annals of internal medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundViolent injury survivors are at risk for revictimization. The St. Louis area hospital-based violence intervention program (HVIP), Life Outside of Violence (LOV), is the first multisystem, region-wide HVIP in the United States.
objectiveTo describe the LOV program during its pilot phase and evaluate violent reinjury 1 year after index injury among LOV participants.
designPilot observational cohort study of violently injured patients.
settingData were queried from the program's multisystem data repository, which contains individual encounter-level data for all violent injury visits from the 2 adult and 2 pediatric LOV-partner level 1 trauma hospitals.
participantsPatients eligible for LOV who were violently injured between 15 August 2018 and 31 December 2022 and enrolled in LOV, matched to control participants of nonenrolled LOV-eligible patients selected from the data repository using propensity score matching.
interventionParticipation in the LOV program. MEASUREMENTS: Sociodemographic characteristics, predictors of LOV enrollment, and returning to a LOV partner hospital with a violent reinjury within 1 year of index injury. The probability of violent reinjury and 95% CIs were compared between LOV participants and control participants using Kaplan-Meier estimates.
results233 of 3744 eligible patients enrolled in LOV. Of 198 LOV-enrolled participants matched to 388 nonenrolled control participants, Kaplan-Meier estimates for 1-year probability of reinjury were 7.6% (95% CI, 3.8% to 11.2%) among LOV participants and 7.4% (CI, 4.8% to 10.0%) in control participants. LIMITATION: This pilot study cannot provide precise estimates of LOV intervention efficacy.
conclusionAlthough no informative evidence of differences in reinjury probability for LOV participants was seen, findings suggest that the overwhelming risk in which our patients are immersed cannot be overcome by an approach scaled for individual-level impact.
