Distinctive Inflammatory Traits of Parvovirus B19 Infection Associated with Persisting Autoimmunity.
Observational study in Viruses, 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
backgroundAdult parvovirus B19 (B19V) infection occurs with cyclic outbreaks and can be associated with inflammatory manifestations mimicking or heralding the onset of systemic autoimmune diseases. Little is known about clinical traits distinguishing patients with transient vs. persisting manifestations.
methodsLeveraging data from the 2024 B19V infection outbreak, we set up a retrospective, multicentre, observational study investigating the epidemiology and clinical phenotypes of patients with B19V infection presenting to tertiary care for immune-mediated manifestations, including patients with pre-existing autoimmunity.
resultsA total of 39 B19V infections were identified, yielding an annual incidence of 1.78 cases/1000 patients. Autoimmune rheumatic diseases were pre-existing in 7/39 and newly diagnosed in 5/39. One patient was hospitalised. Arthritis was more frequent in new-onset (89%) than in pre-existing (14%;
conclusionB19V-associated new-onset autoimmunity may occur in one in six cases observed in tertiary immunology care, show distinct clinical features, and require significant immunosuppression.
