Stool Glial Fibrillary Acidic Protein Is Elevated in Progressive Multiple Sclerosis.

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
objectivesThe gut microbiota and altered intestinal physiology have been implicated in multiple sclerosis (MS). Enteric glial cells regulate enteric nervous and immune function and express glial fibrillary acidic protein (GFAP) and S100β. Serum GFAP and neurofilament light chain can predict disease worsening; however, no clear markers differentiate relapsing from progressive disease.
methodsTo investigate enteric glial function in MS, we measured stool GFAP (st-GFAP) using an enzyme-linked immunosorbent assay in 31 healthy controls (HCs), 77 patients with relapsing remitting MS (RRMS), and 53 patients with progressive MS (ProgMS). Participants underwent clinical follow-up at 2 and 5 years after stool donation.
resultsWe found higher st-GFAP levels in patients with ProgMS compared with those with RRMS and HCs. St-GFAP was positively correlated with baseline Expanded Disability Status Scale (EDSS) score, 25-foot walk time, and an increased EDSS score at 2 and 5 years. We found enteric glial hyperplasia in the colonic mucosa of a patient with primary progressive MS, as indicated by GFAP and S100β immunoreactivity, an effect not observed in duodenum tissue in patients with RRMS from our Milan cohort. St-GFAP in patients with ProgMS was negatively associated with DISCUSSION: These exploratory data indicate an altered enteric glial phenotype in patients with ProgMS and suggest that st-GFAP may be a prognostic biomarker.
