Isolated ventricular septal defect is not a risk factor for celiac disease: evidence from a large real-world data cohort of 493,382 children.

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: Ventricular septal defect (VSD) is one of the most common congenital heart defects in children. Celiac disease (CD) is known to cluster with autoimmune conditions and chromosomal syndromes, but it remains unclear whether isolated VSD is independently associated with CD. Methods: We performed a population-based retrospective cohort study using electronic records from Clalit Health Services. Children aged 0-10 years were followed for up to 10 years to identify incident cases of CD. Multivariable Cox proportional hazards models were used to estimate adjusted hazard ratios (HRs) with 97.5% confidence intervals (CIs) for the association between VSD and CD. The models were adjusted for age, sex, type 1 diabetes mellitus, autoimmune diseases, immunodeficiency, and chromosomal anomalies. Results: The Cox model included 493,382 children. VSD was not independently associated with an increased risk of CD (HR 1.25, 97.5% CI 0.85-1.82). In contrast, established comorbidities showed strong associations with CD: type 1 diabetes mellitus (HR 10.26, 97.5% CI 8.15-12.91), chromosomal anomalies (HR 5.20, 97.5% CI 3.67-7.37), and autoimmune diseases (HR 2.07, 97.5% CI 1.39-3.10). Conclusion: In this large real-world data, isolated VSD was not an independent risk factor for CD, whereas type 1 diabetes mellitus, chromosomal anomalies, and other autoimmune diseases were strongly associated with CD. These findings do not support routine CD screening based solely on the presence of VSD in children.
