Prevalence of Weapons in the Health Care Setting: A Systematic Review and Meta-Analysis.
Review in Mayo Clinic proceedings. Innovations, quality & outcomes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
This study aimed to systematicically evaluate and quantify the prevalence of weapons in the health care setting. A systematic search of MEDLINE, Embase, Scopus, Web of Science, CINAHL, and EBSCO MegaFILE was performed from inception to January 12, 2024. The primary outcome was the prevalence of weapons in the health care setting on patients and/or visitors. Prevalence was pooled across studies and estimated using a random effects model. Subgroup analyses were done based on types of weapons, characteristics of weapon carriers, weapons screening/detection technology, and screened population characteristics. A total of 14 observational studies were included. All studies were from the United States and were published between 1984 and 2023. Weapons prevalence ranged from 0.4% to 26.3% among populations screened in the included studies. The overall pooled weapons prevalence was 4.0% (95% CI, 2.0%-7.8%). Most weapons were bladed (3.8%; 95% CI, 1.5%-8.9%), followed by other weapons (0.6%; 95% CI, 0.3%-1.3%), and firearms (0.1%; 95% CI, 0.02%-0.5%;
