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

purposeCannabis has been used for thousands of years in many cultures for the treatment of several ailments including pain. The benefits of cannabis are mediated largely by cannabinoids, the most prominent of which are tetrahydrocannabinol (THC) and cannabidiol (CBD). As such, THC and/or CBD have been investigated in clinical studies for the treatment of many conditions including neuropathic pain and acute or chronic inflammation. While a plethora of studies have examined the biochemical effects of purified THC and/or CBD, only a few have focused on the effects of full-spectrum cannabis plant extract. Accordingly, studies using purified THC or CBD may not accurately reflect the potential health benefits of full-spectrum cannabis extracts. Indeed, the cannabis plant produces a wide range of cannabinoids, terpenes, flavonoids, and other bioactive molecules which are likely to contribute to the different biological effects. The presence of all these bioactive molecules in cannabis extracts has garnered much attention of late especially with regard to their potential role in the treatment of neuropathic pain associated with multiple sclerosis.

methodsLiterature review was performed to further understand the effect of clinically used full-spectrum cannabis extract in patients with multiple sclerosis.

resultsHerein, the current knowledge about the potential beneficial effects of existing products of full-spectrum cannabis extract in clinical studies involving patients with multiple sclerosis is extensively reviewed. In addition, the possible adverse effects associated with cannabis use is discussed along with how the method of extraction and the delivery mechanisms of different cannabis extracts contribute to the pharmacokinetic and biological effects of full-spectrum cannabis extracts.Herein, the current knowledge about the potential beneficial effects of existing products of full-spectrum cannabis extract in clinical studies involving patients with multiple sclerosis is extensively reviewed.
