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

Evidence suggests the involvement of the cannabinoid system in the pathogenesis of multiple sclerosis (MS). We studied cannabinoid receptor (CB)1 and CB2 receptor gene expression in B, natural killer (NK) and T cells from MS patients before and after 1 year of interferon beta therapy, and compared these levels to those of healthy controls. We also measured the production of the endocannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG) and the gene expression of the endocannabinoid-degrading enzyme fatty acid amide hydrolase (FAAH) in these cells. Prior to interferon therapy, MS patients showed significantly elevated CB2 expression in B cells, but not in T or NK cells. These levels decreased gradually within 6 months to 1 year of interferon treatment. CB1 expression was elevated in all cell subsets, but only reached statistical significance in T cells; all levels decreased progressively over time. Before treatment, AEA but not 2-AG levels were significantly elevated in the three cell populations; after 1 year of treatment, all values decreased to control levels. The expression of FAAH was unchanged. The different expression of cannabinoid receptor genes and the increased level of AEA in lymphocytes point to a possible role of the cannabinoid system in MS immune response and its modulation by interferon.
