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

backgroundThe intestinal mucosal barrier plays an important role in the pathophysiology of inflammatory bowel disease (IBD), with mucins being key components of this barrier. Classified as either transmembrane or secreted, these highly glycosylated proteins protect the mucosal barrier while also influencing barrier integrity. Given their indispensable role in maintaining the intestinal mucosal barrier, mucins are compelling candidates for the evaluation of barrier dysfunction. Numerous studies have investigated mucins in the context of IBD, but a clear consensus regarding their expression, polymorphisms, and post-translational modifications is missing. This systematic review summarizes mucin alterations at the transcriptional, translational, and post-translational levels in the presence/absence of intestinal inflammation in IBD patients.

methodsTo this end, PubMed, Scopus, and Web of Science were searched for studies published between February 1993 and January 2025, yielding 69 articles eligible for inclusion.

resultsThe expression of MUC1, MUC5AC, and MUC6 was reported to be upregulated at both RNA (isoform) and protein level, in contrast to MUC12, which exhibited reduced expression in inflamed mucosa only at RNA isoform level. MUC2 was the only mucin consistently downregulated at the protein level, despite unchanged mRNA expression, whereas polymorphisms of MUC2, MUC3A, MUC4, MUC13, MUC19, MUC21, and MUC22 were associated with susceptibility to Crohn's disease, ulcerative colitis, or IBD in general. Post-translational modifications, such as hypoglycosylation of MUC1 and MUC2, as well as a reduction of mucin sulphation of MUC2 were reported.

conclusionTogether, these findings underscore the involvement of mucins in IBD and point to their potential as biomarkers for barrier dysfunction.
