UK Medical Cannabis Registry: An Analysis of Outcomes of Medical Cannabis Therapy for Hypermobility-Associated Chronic Pain.
Article in ACR open rheumatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveThe study aims to evaluate the clinical outcomes in patients with hypermobility spectrum disorder (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) with chronic pain following treatment with cannabis-based medicinal products (CBMPs).
methodsThis was a case series conducted with the UK Medical Cannabis Registry. The primary outcomes were changes in the following validated patient-reported outcome measures at 1, 3, 6, 12, and 18 months compared with baseline: Short-Form McGill Pain Questionnaire 2 (SF-MPQ-2), pain visual analog scale score (Pain-VAS), Brief Pain Inventory (BPI), five-level EQ-5D (EQ-5D-5L), Single-Item Sleep Quality Scale (SQS), General Anxiety Disorder Seven-Item Scale (GAD-7), and Patient Global Impression of Change. The incidence of adverse events was analyzed as secondary outcomes. Statistical significance was defined as P <0.050.
resultsA total of 161 patients met inclusion criteria. Improvements were observed in BPI severity and interference subscales, SF-MPQ-2, and Pain-VAS (P < 0.001). Changes were also seen in the EQ-5D-5L index value, SQS, and GAD-7 (P < 0.001). A total of 50 patients (31.06%) reported one or more adverse event with a total incidence of 601 (373.29%). The most frequent rating for adverse events was moderate (n = 258; 160.25%), with headache being the most common (n = 44; 27.33%).
conclusionAn association was identified between patients with HSD/hEDS with chronic pain and improvements in pain-specific and general health-related quality of life following the commencement of CBMPs. CBMPs were also well tolerated at 18 months. These findings must be interpreted within the context of the limitations of study design but add further weight to calls for randomized controlled trials.
