UK Medical Cannabis Registry: An Updated Analysis of Inflammatory Arthritis.

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
Aim: Cannabis-based medicinal products (CBMPs) are an emerging therapeutic option for pain in inflammatory arthritis, yet clinical evidence remains limited. This study aimed to evaluate changes in pain-specific and general health-related outcomes in patients with inflammatory arthritis treated with CBMPs and to characterize the safety profile by examining the incidence and nature of adverse events. Methods: Patients treated with CBMPs for inflammatory arthritis-associated pain for ⩾24 months were identified from the UK Medical Cannabis Registry. Primary outcomes included changes in patient-reported measures: Brief Pain Inventory (BPI), Pain Visual Analogue Scale (Pain VAS), Short-Form McGill Pain Questionnaire 2 (SF-MPQ-2), EuroQol 5-dimension 5-level (EQ-5D-5L), Generalized Anxiety Disorder-7 (GAD-7), and Single-Item Sleep Quality Scale (SQS) at 1, 3, 6, 12, 18, and 24 months vs baseline. Adverse events were recorded and analysed. Statistical significance was set at Results: A total of 192 patients met inclusion criteria. The CBMP initiation was associated with improvements in BPI Interference, BPI Severity, Pain VAS, SF-MPQ-2, SQS, and EQ-5D-5L index values at all follow-up time points ( Conclusion: The CBMP therapy was associated with reductions in pain and improvements in health-related quality of life among individuals with inflammatory arthritis. Although causality cannot be inferred from this observational design, these findings support the need for randomized controlled trials to determine the efficacy of CBMPs for inflammatory arthritis-related pain.
