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

objectiveThis study involves a pilot investigation of associations between marijuana and synthetic cannabis use with PTSD symptoms among a young adult sample of U.S. veterans.

methodIn a cross-sectional survey of a community sample of 790 young adult U.S. veterans, we assessed demographics, combat severity, marijuana and synthetic cannabis use, expectancies of marijuana use, and PTSD symptoms.

resultsOverall, 61.8% and 20.4% of our sample reported lifetime and past-month marijuana use, whereas 17.0% and 3.4% reported lifetime and past-month synthetic cannabis use. Veterans screening positive for PTSD were more likely to use marijuana and synthetic cannabis in their lifetime and in the past month. Positive PTSD screens, as well as greater expectancies that marijuana leads to relaxation and tension reduction, were associated with past-month marijuana use in logistic regression analyses. Expectancies moderated the relationship between PTSD and marijuana use, such that those with positive PTSD screens reporting higher levels of relaxation and tension-reduction expectancies were most likely to report past-month marijuana use.

conclusionsOur findings suggest an association of PTSD symptoms with marijuana and synthetic cannabis use among young adult U.S. veterans. Future research should further investigate the link between PTSD and marijuana use, as well as the rates and consequences of synthetic cannabis use among veterans.
