Microscopic Polyangiitis in a Nonagenarian: Diagnostic and Therapeutic Challenges in Geriatric Vasculitis.
Article in Annals of geriatric medicine and research, 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
Microscopic polyangiitis (MPA) is a rare antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis that poses unique diagnostic and therapeutic challenges in seniors. We describe a 90-year-old female with diabetes, hypertension and heart failure who presented with anasarca and rapid renal failure. Evaluation revealed myeloperoxidase-ANCA positivity, and renal biopsy confirmed pauci-immune crescentic glomerulonephritis. Her course was complicated by anemia and deep vein thrombosis. She was managed with high-dose corticosteroids, rituximab, and supportive hemodialysis, achieving improvement in renal function. This case highlights how comorbidities may obscure recognition of vasculitis and how assessment of frailty and baseline function are essential in weighing risks of immunosuppression in older adults. Clinicians should maintain vigilance for ANCA-associated vasculitis in older adults with unexplained renal decline and tailor therapy to balance disease control with vulnerability to treatment toxicity.
