1 · What the graph read from 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.

2 · The registry

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

objectivesIn 2013, the state of Maryland passed the Firearms Safety Act limiting the private sales of handguns, which did not apply to long guns often used for hunting (e.g., rifles and shotguns). This decreased the accessibility of handguns relative to long guns. We assessed the frequency of long gun suicides in the years before and after the policy change during winter season, which encompasses hunting season in Maryland.

methodsWe performed a retrospective analysis on all 4107 well-characterized adult suicides caused by firearms in Maryland from 2003 through 2019. Logistic regression was performed, stratifying by decedent sex, race, and age.

resultsWhile handgun suicides decreased in the period after 2013's Firearm Safety Act (p < 0.008), wintertime long gun suicides increased after 2013 (p < 0.004). Caucasian race (p < 0.006), male sex (p < 0.005), and middle age (p < 0.001) were significantly associated with wintertime long gun suicides after 2013.

conclusionOur findings suggest that while the 2013 Firearms Safety Act decreased handgun suicides significantly, it did not reduce long gun suicides and there may even have been replacement with long guns during hunting season, when rifles are out and accessible. This association was most prominent among the demographics most likely to hunt (Caucasian, middle-aged, and male).
