Prevalence and Clinical Relevance of Anti-FcεRI Autoantibody in Crohn's Disease.
Article in Journal of asthma and allergy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Mast cells can be activated in various ways and were shown to be involved in the development of Crohn's disease (CD). The diagnosis of CD is still challenging, and seeking novel biomarkers is a worthwhile endeavor. Methods: An indirect enzyme-linked immunosorbent assay (ELISA) was successfully established for semi-quantitative detection of IgG anti-FcεRI in serum using human FcεRIα coated microplates and an enzyme-labeled anti-human IgG as secondary antibodies. The optimal working conditions were explored, followed by conducting the method evaluation. The serum samples and clinical data of 117 CD patients and 75 healthy controls were collected. IgE was measured by the rate turbidity turbidimetry; IgG anti-IgE and IgG anti-FcεRI were detected by ELISA. IgG anti-pancreatic antibody (PAB) and anti-Saccharomyces cerevisiae antibody (ASCA) were determined by indirect immunofluorescence assay. Data were analyzed concerning the clinical characteristics. Results: IgG anti-FcεRI was an effective marker for CD ( Conclusion: An ELISA for the detection of anti-FcεRI was established and validated, which may contribute to facilitating research on Crohn's diseases. Anti-FcεRI positive CD patients were associated with higher disease activity indices, suggesting its potential value in the diagnosis and management of CD.
