Attitudes, perceptions, and use of marijuana in youth with multiple sclerosis.
Article in Journal of neurology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
backgroundStudies have shown a negative impact on cognition and brain volume in marijuana-using adult multiple sclerosis (MS) patients and healthy adolescents. Given that onset of MS during childhood and adolescence negatively impacts brain growth and the normal maturation of neuronal networks, the addition of marijuana exposure in these youth may be even more harmful.
objectiveDetermine attitudes toward and prevalence of recreational marijuana use in MS youth.
methodsWe surveyed 52 consecutive pediatric-onset MS patients from three pediatric MS centers in the United States. Participants answered a structured questionnaire to capture attitudes toward marijuana and personal use habits, if present.
resultsNearly half reported use of marijuana, with the majority beginning to use in mid-to-late adolescence. The most popular reasons for using marijuana were relaxation (72%), improvement of medical problems (64%), and stress reduction (52%). Over half (64%) of marijuana users perceived it to have negative effects on memory and focus. Cost and access were not barriers to use, despite all respondents being less than age 21.
conclusionYouth with MS endorse recreational marijuana as safe, and many use marijuana frequently despite appreciating a negative impact on memory. More detailed understanding of the long-term impact of marijuana use in youth with MS is needed.
