Gastrointestinal lesions of eosinophilic granulomatosis with polyangiitis: a prediction model and clinical patterns.
Article in Arthritis research & therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveSevere gastrointestinal lesions are associated with a poor prognosis in eosinophilic granulomatosis with polyangiitis (EGPA). The goal of this study was to develop an effective predictive model for gastrointestinal lesions and to examine clinical patterns, associated factors, treatment, and outcomes of gastrointestinal lesions in EGPA.
methodsWe retrospectively enrolled 165 EGPA patients. The independent associated factors were analyzed using multivariate logistic regression. A nomogram was conducted to quantify the predictive factors. The correlation between different organ lesions was calculated to explore the clinical patterns.
resultsA total of 52 patients had gastrointestinal lesions, and 22 developed severe disorders. Common manifestations included abdominal pain (78%), diarrhea (40.4%), and nausea and/or vomiting (32.7%). Severe gastrointestinal lesions included hemorrhage (26.9%), ulcers (17.3%), obstruction (9.6%), and pancreatitis (5.8%). Eosinophilic tissue infiltration, weight loss, and myalgia were independently associated with gastrointestinal involvement. Patients with severe gastrointestinal lesions had a shorter duration from initial symptoms to EGPA diagnosis, less frequent asthma, and ear-nose-throat involvement, and were more likely to receive methylprednisolone pulse. Weight loss, central nervous system involvement, myalgia, and eosinophilic tissue infiltration were retained in the nomogram. An eosinophil ratio of over 19.2% identified gastrointestinal lesions. Significantly more patients with gastrointestinal involvement had a Five Factor Score ≥ 2. Five well-defined clinical models were identified, including the brain-gut pattern.
conclusionsSevere gastrointestinal lesions are common in EGPA and early detection is critical. Eosinophils are an important factor associated with gastrointestinal involvement of EGPA. We developed a model to predict the risk of gastrointestinal lesions. The brain-gut pattern might deserve further investigation in EGPA.
