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

backgroundInformal recycling refers to the street-based collection of discarded materials for reuse, resale, or return to a recycling facility for money. While qualitative research has explored experiences and perceptions of informal recycling, little is known about the scope and exposures associated with informal recycling among people who use drugs (PWUD).

methodsUsing data from two prospective longitudinal cohorts of PWUD, we examined the prevalence of informal recycling and its association with social, structural and health risks, including criminal justice system involvement.

resultsBetween June 2010 and May 2015, of 1664 participants, 557 (33.5%) reported engaging in informal recycling during the study period. In multivariable generalised estimating equations (GEE) analyses, informal recycling was positively associated with injection drug use (Adjusted Odds Ratio (AOR) = 1.43, 95% Confidence Interval (CI) 1.21-1.68), public injection (AOR = 1.27, 95% CI 1.09-1.49), methamphetamine use (AOR = 1.35, 95% CI 1.05-1.72), difficulty finding harm reduction equipment (AOR = 1.16, 95% CI 1.02-1.32), and police interactions (AOR = 1.35, 95% CI 1.18-1.55). Sub-analyses revealed PWUD engaged in informal recycling were more likely to be told to move on, ticketed, stopped for jaywalking, and directed to services by police.

conclusionsThese findings suggest informal recycling as a situated practice for PWUD, with potential indications for higher-risk drug use, experiencing greater surveillance, and difficulty accessing health and addiction treatment services. This research highlights the significance of the broader risk environment and the need for health-promoting policies for socioeconomically marginalised PWUD engaged in informal recycling.
