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

INTRODUCTION AND

aimsCrack cocaine pipe sharing is associated with various health-related harms, including hepatitis C transmission. Although difficulty accessing crack pipes has been found to predict pipe sharing, little is known about the factors that limit pipe access in settings where pipes are provided at no cost, albeit in limited capacity. Therefore, we investigated crack pipe access among people who use drugs in Vancouver, Canada. DESIGN AND

methodsData were collected through two Canadian prospective cohort studies. Generalised estimating equations with logit link for binary outcomes were used to identify factors associated with difficulty accessing crack pipes.

resultsAmong 914 participants who reported using crack cocaine, 33% reported difficulty accessing crack pipes. In multivariate analyses, factors independently associated with difficulty accessing crack pipes included: sex work involvement [adjusted odds ratio (AOR) = 1.57; 95% confidence interval (CI): 1.03-2.39], having shared a crack pipe (AOR = 1.69; 95% CI: 1.32-2.16), police presence where one buys/uses drugs (AOR = 1.47; 95% CI: 1.10-1.95), difficulty accessing services (AOR = 1.74; 95% CI: 1.31-2.32) and health problems associated with crack use (AOR = 1.37; 95% CI: 1.04-1.79). Reasons given for difficulty accessing pipes included sources being closed (48.2%) and no one around selling pipes (18.1%). DISCUSSION AND

conclusionsA substantial proportion of people who smoke crack cocaine report difficulty accessing crack pipes in a setting where pipes are available at no cost but in limited quantity. These findings indicate the need for enhanced efforts to distribute crack pipes and address barriers to pipe access.
