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

It is critical to have naloxone readily available in the event of an opioid overdose. This study examines the prevalence of owning and carrying naloxone and factors associated with ownership and carriage among people who use opioids in Baltimore, Maryland, from December 2022 to January 2025. Among the 780 community-recruited study participants who were aged 18 years or older and currently used non-prescription opioids, most (78.2 %) reported owning naloxone, with the majority (69.4 %) keeping it at their residence. While 41.8 % of participants reported always having naloxone available when using drugs, 13.5 % never did. Only 27.0 % were carrying it with them at the time of the interview. Frequent heroin/fentanyl use (aOR: 2.07; 95 % CI: 1.36-3.16) and reporting lower difficulty accessing naloxone (aOR: 2.37; 95 % CI: 1.85-3.05) significantly increased the likelihood of owning naloxone. Experiencing homelessness in the past six months (aOR: 2.09; 95 % CI: 1.40-3.12) and perceiving poor neighborhood treatment due to drug use (aOR: 1.27, 95 % CI: 0.1.08-1.49) increased odds of currently carrying naloxone. Although naloxone distribution programs have successfully improved access, substantial gaps remain in consistent naloxone carriage, necessitating targeted interventions addressing barriers to carriage, including drug use stigma.
