Granulomatosis With Polyangiitis: A Case of a 62-Year-Old Female Presenting With a Fever of Unknown Origin.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Fever of unknown origin (FUO) continues to present diagnostic challenges despite advancements in medical science. Granulomatosis with polyangiitis (GPA), a rare antineutrophil cytoplasmic antibody (ANCA)-associated small-vessel vasculitis characterized by necrotizing granulomas, is an uncommon but important cause of FUO. This case report describes a 62-year-old female presenting with prolonged fever, malaise, and nonspecific systemic symptoms, ultimately diagnosed with GPA after extensive investigations, including positive C-ANCA and anti-proteinase-3 serology and imaging revealing a cavitating lung lesion. The patient's symptoms improved following immunosuppressive therapy with corticosteroids and rituximab. This case highlights the necessity of considering vasculitis, particularly GPA, early in the differential diagnosis of FUO to enable timely treatment and prevent serious complications.
