Characterising resilient and at-risk neighbourhoods with lower-than-expected and higher-than-expected firearm injuries and fatalities in Pittsburgh, Pennsylvania.

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
introductionFirearm injuries and fatalities adversely affect individual and community health and are important public health issues. Identifying factors that protect against firearm violence and related harms is needed. We aimed to identify neighbourhoods with lower-than-expected and higher-than-expected firearm injuries and fatalities based on social vulnerability and their differing structural and social characteristics.
methodsWe used Gun Violence Archive data from the RISE Lab Firearm Injury Data Hub to estimate firearm injury and fatality counts between 2015 and 2020 in Pittsburgh, Pennsylvania. We used a negative binomial regression model to estimate the relationship between the Centers for Disease Control and Prevention's social vulnerability index and firearm injuries and fatalities, and the residual percentile method to identify neighbourhoods with lower (resilient) and higher (at-risk) counts than expected based on social vulnerability. T-tests were used to compare resilient and at-risk neighbourhoods for 158 US Census American Community Survey demographic, socioeconomic, housing and transportation variables.
resultsResilient neighbourhoods (n=19, bottom quartile residuals) had lower rates of firearm injuries and fatalities (p=0.0002) compared with at-risk neighbourhoods (n=19, top quartile residuals). Resilient and at-risk neighbourhoods differed for 2 (per cent male never married and female widowed) of the variables included in the analyses.
conclusionsSome neighbourhoods, despite facing risk factors, experienced fewer firearm injuries and fatalities than would be expected based on neighbourhood social vulnerability. Existing sources of secondary data on neighbourhoods may fail to adequately capture potential factors that prevent against firearm violence and to measure resilience in thriving neighbourhoods. Future community-engaged studies are needed to understand and measure neighbourhood-level protective factors.
