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
backgroundBoth eosinophilic oesophagitis (EoE) and chronic rhinosinusitis (CRS) are type 2 inflammatory conditions sharing pathogenic mechanisms, therapeutic responses and atopic associations. Data on the prevalence of CRS in EoE patients is missing.
aimsOur aim was to assess the prevalence of CRS-type symptoms in EoE patients, the quality of life and shared characteristics of patients with both diseases.
methodsWe assessed the point prevalence of CRS in Swiss Eosinophilic Esophagitis Cohort Study patients using a validated screening questionnaire comprising four symptom-based diagnostic criteria. CRS was defined based on symptoms only (definition A) and including self-reported CRS diagnosis by a physician (definition B). Point prevalence was tested against population prevalence using two-sided binomial tests. Secondary outcomes were compared between patients with and without CRS. Multivariable logistic regression models were built to adjust for confounders.
results211 patients (54%) answered our questionnaire. Prevalence of CRS-type symptoms was 21.8% (definition A) or 25.1% (definition B), compared to 8.71% in the general population (p < 0.0001). CRS status was associated with increased EoE symptom severity. This association persisted after adjustment in multivariable logistic models, most consistently under definition A. 25% reported that their CRS symptoms were more debilitating than their EoE symptoms.
conclusionCRS-type symptoms are two- to three times more prevalent in EoE patients than in the general population and substantially impact quality of life. Our findings indicate that CRS may be under-diagnosed in EoE and support routine CRS screening in EoE patients and cross-speciality collaboration, particularly as both conditions benefit from therapeutic strategies targeting type 2 inflammation.
