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

objectivesTo describe the geographic distribution of naloxone kits in Rhode Island using multiple measures of naloxone saturation to inform future naloxone distribution efforts.

methodsNaloxone distribution by region from 2022 to 2024 was compared by kits dispensed per fatal overdose, per non-fatal overdose, and per 100,000 residents using data on naloxone kits distributed by community-based organizations in Rhode Island. These measures were also compared to the published PROFOUND model estimates which provide naloxone distribution guidelines using a demand-based approach that prioritizes distribution to areas where people are at greatest risk of opioid overdose. This study defined naloxone saturation as a region having higher than the statewide ratio for non-fatal/fatal overdose, kits per 100,000 residents, or the PROFOUND recommendation for the region.

resultsFrom 2022 to 2024, community-based agencies distributed 124,606 naloxone kits. Across the four measures, disparities in geographic distribution were similar, however, naloxone distribution by overdose burden varied widely. Regions with a higher burden of overdoses generally had higher naloxone distribution; however, distribution varied substantially across the state, even among regions with similar overdose burden. Three of Rhode Island's ten regions consistently had the lowest naloxone distribution among all four measures and were selected for interventions to increase distribution.

conclusionsPublic health jurisdictions can explore geographic gaps in naloxone kit distribution to help ensure equitable distribution of naloxone and identify areas to increase distribution efforts.
