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

Introduction: Many patients report adverse symptoms following wheat/gluten consumption. As "Self-Reported Wheat/Gluten Sensitivity" lacks gold-standard biomarkers, characterizing biological profiles in Western populations is essential for precision management. This study analyzes immunogenetic (HLA-DQ) and serological (IgG) patterns in a real-world clinical cohort. Methods: A retrospective observational study used Real-World Evidence (RWE) from 100 symptomatic individuals (2019-2024) selected via non-probabilistic convenience sampling. Participants underwent HLA-DQ genotyping and serum IgG reactivity testing for wheat/gluten via a validated ELISA-based assay. Data normality was formally assessed using the Shapiro-Wilk test, revealing a non-parametric distribution ( Results: A 100% cumulative frequency of HLA-DQ susceptibility variants was observed. The immunogenetic landscape revealed complex heterozygosity: DQ1 was most prevalent (56%), followed by DQ2 (54%), DQ3 (40%), and DQ8 (33%). DQ8 ( Discussion: Findings reveal a ubiquitous HLA-DQ frequency, suggesting a consistent genetic background in symptomatic individuals that significantly exceeds prevalence in the general Western population. This enriched 'mosaic' may facilitate immune activation. Furthermore, the observed IgG cross-reactivity validates the 'wheat/gluten complex' as a synchronized immunological unit, supporting a transition toward biomarker-informed nutrition in real-world settings.
