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

backgroundInterest in and use of marijuana by persons with multiple sclerosis (MS) has increased. While potential benefits have been reported, so have concerns about potential risks. Few large studies have been conducted about the perceptions and current usage of marijuana and medical cannabinoids in persons with MS.

methodsParticipants in the North American Research Committee on Multiple Sclerosis (NARCOMS) registry were surveyed in 2014 regarding legality and history of marijuana usage, both before and after diagnosis with MS.

resultsA total of 5,481 participants responded, with 78.2% female, 90% relapsing disease at onset, and a current mean age of 55.5 (10.2) years. Sixty-four percent had tried marijuana prior to their MS diagnosis, 47% have considered using for their MS, 26% have used for their MS, 20% have spoken with their physician about use, and 16% are currently using marijuana. Ninety-one percent think marijuana should be legal in some form. Men, those with higher disability, current and past nicotine smokers, and younger age were associated with a higher likelihood of current use.

conclusionsThe majority of responders favor legalization and report high interest in the use of marijuana for treatment of MS symptoms, but may be reluctant to discuss this with health care providers. Health care providers should systematically inquire about use of marijuana.
