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

backgroundSustained abstinence is currently the only accepted end-point for pharmacotherapy trials for most substance use disorders (SUD), with the exception of alcohol. Despite recent efforts, the identification of a non-abstinence alternative as a clinically meaningful end-point for drug use trials has been elusive. ARGUMENT AND ANALYSIS: The current standard for establishing a clinically meaningful outcome in SUD trials is to demonstrate that a reduction in drug use is associated with improvement in long-term functioning, but data indicate relatively weak associations between drug use and various psychosocial problem domains. This may be because assessments used most commonly to measure an individual's functioning do not specify whether aspects of functioning are a direct consequence of drug use. The acceptance of a non-abstinence-based end-point for alcohol use disorder trials was supported in part through associations with reductions in alcohol-related consequences, although measures designed to assess the direct consequences of drug use are rarely included in drug treatment efficacy trials.

conclusionsThe field of substance use disorders should include measures of negative psychosocial and health consequences of drug use, as opposed to overall functioning, in the effort to establish meaningful non-abstinence-based end-points.
