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

backgroundDrug use stigma among service providers has been recognized as a barrier to improving the accessibility and outcomes of addiction treatment. This study examined the stigmatizing attitudes towards people who use drugs (PWUD) among service providers in methadone maintenance treatment (MMT) clinics in China and its associated factors.

methodsThe cross-sectional study used the baseline data of a randomized intervention trial conducted in China, and the data were collected from January 2012 to August 2013. A total of 418 MMT service providers were included in the study. Stigma towards PWUD was measured via a 10-item scale embedded in two case vignettes (PWUD and non-PWUD). The Wilcoxon signed-rank test was performed to evaluate the vignette difference for each item of the scale. The linear mixed model was used to identify the adjusted association between drug use stigma and other interested variables including demographics, professional background, and MMT knowledge of the service providers.

resultsThe Wilcoxon signed-rank tests showed that the participants had a higher level of stigmatizing attitudes towards PWUD than non-PWUD (p-value<0.001 for all items of the stigma scale). The linear mixed model identified that the reception of national MMT training was associated with a lower degree of drug use stigma (estimate=-1.79; 95% CI: -3.13, -0.45; p-value = 0.009).

conclusionThe findings of the study provide evidence of the existence of drug use stigma among MMT providers in China. The expansion of national-level training and the development of stigma reduction interventions are needed to address this issue.
