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

objectiveMany rural people who inject drugs do not use syringe service programs (SSPs). In addition, people who use drugs but do not inject may perceive that SSPs are not intended for their use. Harm reduction vending machines (HRVMs) may be preferred by some individuals. This study examines attitudes and preferences regarding HRVMs to consider possibilities for enhancing the reach of harm reduction services.

methodStructured surveys were conducted with 712 people who use drugs in two rural Appalachian counties in Kentucky. Participants rated the acceptability/appropriateness of SSPs and HRVMs; HRVM preference was the difference between the two scales. Linear regression models estimated SSP acceptability/appropriateness, HRVM acceptability/appropriateness, and HRVM preference across five groups differentiated by their SSP use, injection, and syringe sharing behaviors.

resultsAverage ratings for acceptability/appropriateness of the SSP and HRVM were favorable (4.17 and 4.49, respectively, on a scale from 1 to 5), but HRVM acceptability was significantly higher (

conclusionsHRVMs may engage people not currently using SSP services and those who use drugs without injecting, thus expanding the reach of harm reduction services, particularly in rural areas.
