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

backgroundUp-to-date information regarding the scope and impact of cannabinoid use among persons with MS (PwMS) is necessary to guide clinical practice and cannabinoid research.

objectivesTo assess utilization patterns and perceived impact of cannabinoid use among a national cohort of PwMS.

methodsData collected were part of a nationwide survey to characterize pain in PwMS. Items included questions about current/recent cannabinoid use, reasons for use, preferred THC/CBD formulations, and perceived benefits/side effects. PROMIS short-forms assessed symptom severity. Pain phenotype was assessed with the painDETECT questionnaire and FMSurvey Criteria Questionnaires.

resultsAmong n = 1,027 respondents, 42% endorsed recent cannabinoid use, of which 18% endorsed healthcare provider guidance regarding use. PROMIS scores (except cognitive abilities), and pain centralization and neuropathic pain scores, were higher among recent/current users (each p < 0.0001). Sleep and pain were the most frequently reported reasons for use. Benefit from cannabinoids for sleep and pain were strongly correlated (r = 0.65, p < 0.0001). For those who expressed a preference for specific THC/CBD ratios, CBD-predominant formulations were favored.

conclusionCannabinoid use is common in PwMS, despite a paucity of provider guidance. The range of perceived benefits, and potential differential effects of THC and CBD, highlight the need for personalized, evidence-based guidelines regarding cannabinoid use.
