Mass-Forming Variants in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: Diagnostic Complexities in Granulomatous Disease. A Case Report.
Article in ACR open rheumatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
A middle-aged woman presented with a granulomatous breast lesion in 2018. By 2021, antibiotic-resistant pneumonia led to the discovery of granulomatous inflammation in the lung and thyroid. Initially misdiagnosed as Erdheim-Chester disease (ECD), she was treated with interferon without success. Histopathology later ruled out ECD, suggesting an unspecified granulomatous disease, with granulomatosis with polyangiitis (GPA) initially excluded due to negative antineutrophil cytoplasmic antibodies (ANCAs) and foamy histiocytes. In 2023, repeated lung biopsy and PR3-ANCA positivity led to a revised diagnosis of mass-forming GPA. Rituximab therapy resulted in remission. This case highlights the diagnostic complexity of GPA with atypical histopathological features.
