Adolescent firearm injury trends at a Level I trauma center in Washington State, USA, 2011-2021.
Article in BMC pediatrics, 2025. 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
backgroundFirearm-related harm is a pressing public health problem in the United States, particularly among adolescents. While informative, national level data may mask variations in firearm injury incidence across and within states.Publicly available firearm injury data may be limited or unavailable, highlighting the importance of analyzing more granular data to develop or refine tailored interventions shaped by the unique needs and contexts of individual communities.
methodsThis retrospective cohort study used data from a Level I Trauma Center and death records to examine adolescent firearm injury trends in King County, Washington from 2011 to 2021. We calculated incidence rates per 100,000 population for each year of the study period and examined differences by fatality, intent, race, ethnicity, age, and sex.
resultsAnnual incidence rate of overall firearm injury significantly increased during the study period from 18.1 to 24.9 per 100,000 persons (p = 0.003); we observed the highest rate in 2020 (26.5 per 100,000 persons) and the lowest in 2013 (11.5 per 100,000 persons). Nonfatal firearm injuries comprised 71.4% of our sample and had the highest rate in 2020 (18.7 per 100,000 persons), while the rate of fatal firearm injuries was highest in 2021 (8.0 per 100,000 persons). Assault-related firearm injuries were most frequent (73.7%), were primarily nonfatal (81.7%), and significantly increased during the study period (p < 0.001). The rate of self-inflicted injuries surpassed that of unintentional injuries during the study period and the majority were fatal (92.5%). Overall firearm injury incidence rates were highest among adolescents aged 18-19, males, and individuals from racial or ethnic minority groups.
conclusionThe rate of firearm injuries among King County adolescents significantly increased between 2011 and 2021. Our study identified a disproportionate burden of firearm-related harm among King County adolescents who are Black, American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, Latine, male, and aged 18-19, highlighting disparities in firearm injury by demographic subgroups. These findings may assist the development of local evidence-informed prevention and intervention strategies and guide the implementation of existing interventions among adolescents disproportionately impacted by firearm-related harm.
