Review in JGH open : an open access journal of gastroenterology and hepatology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05177003 (Study of the 12-month Efficacy of Stem Cell Injection in Crohn's Disease With Complex Ano-perineal Fistula), which is not on this map. Cited by 25 papers, 7 of them syntheses 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

Perianal fistulas in Crohn's disease (CD) represent a highly debilitating and difficult-to-treat condition. Given emerging supportive evidence, we conducted a systematic review and meta-analysis of all trials/observational studies to establish the safety and efficacy of local injections of mesenchymal stem cells (MSCs). The PRISMA-P statement was applied for planning and reporting, and MEDLINE, EMBASE, Web of Science, Cochrane, CINAHL, ClinicalTrials.gov database, and ECCO 2017 proceedings were searched for published observational studies and one-arm and randomized clinical trials (RCTs). Safety was assessed in terms of acute local/systemic events, long-term events, and relatedness with MSC treatment. Efficacy was evaluated in terms of external and/or radiological closure of fistula tracks. After a review of 211 citations, 23 studies, including 696 participants, were evaluated. Four were RCTs with a total of 483 patients. Overall, fistula closure occurred in 80% of MSC-treated patients. In RCTs, this rate was 64% in the MSC arm and 37% in the control arm (relative risk (RR) = 1.54). Radiological response occurred in 83% of MSC-treated patients. Treatment-related adverse events occurred in 1% of MSC-treated patients, with severe treatment-related adverse events reaching 0% over a median follow-up of 6 months. In RCTs, treatment-related adverse events occurred in 13% in the MSC arm and 24% in the control arm (RR = 0.65). The relapse rate was 0. These results suggest that a local MSC injection is safe and efficacious. Further clinical trials with standardized end-points are required to ensure the timely implementation of this new therapy in the management of perianal CD.
