Review in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07638189 (Pilot Study Using Topical Cannabidiol), which is not on this map. Cited by 29 papers, 1 of them a synthesis that pooled it.

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.

Abstract

We conducted a systematic review to determine the efficacy and safety of cannabidiol (CBD) for chronic pain. The systematic review is according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 checklist. Five databases (PubMed, PubMed Central, Medline, Cochrane Library, and ScienceDirect) were searched using cannabidiol, CBD, hemp, and chronic pain. Inclusion criteria used were studies on adult populations >18 years old; pain symptoms >three months duration; all available preparations of CBD; human studies only; publication in English in the past five years. A total of 2298 articles were found. Inclusion criteria were applied, and quality assessments were done, resulting in 12 publications eligible for the review. CBD and tetrahydrocannabinol (THC), both from Cannabis plants with almost identical chemical structures, attach to the CB receptor, eliciting different effects like the psychoactivity seen on THC but less or none in CBD. Regulations of CBD worldwide differ from each other due to the insufficiency of solid evidence to establish its benefit versus the risks. However, a few studies are showing the benefits of CBD not only for chronic pain but also for sleep improvement and quality of life. In conclusion, CBD is an excellent alternative to an opioid in chronic pain because CBD is non-intoxicating in its pure form. More clinical trials should be done to prove CBD's significance clinically and statistically.
