Clinical Profile of Patients with Urticarial Vasculitis in China: A Retrospective of 142 Cases.
Article in Journal of inflammation 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
Background: Normocomplementemic urticarial vasculitis (NUV) and hypocomplementemic urticarial vasculitis (HUV) share clinical features, notably wheals, yet clear differential diagnostic criteria are lacking. Objective: To describe HUV and NUV features in Chinese inpatients for diagnosis. Methods: Retrospective study (March 2017-June 2024, China) of NUV/HUV patients. We analyzed clinical characteristics, laboratory results, and histological features, and compared drug efficacy. Results: Females constituted the majority of patients with urticarial vasculitis(UV). All patients present with wheals persisting for more than 24 hours, and 76.1% of the wheals exhibited partial or complete non-blanching. Angioedema was more common in patients with HUV than in NUV (44.4% vs 25.0%, Conclusion: Our study identified key factors associated with the occurrence of UV subtypes. For patients with recurrent wheals, complement levels, ESR, and the distribution pattern of immunofluorescence deposits can serve as basis for classifying UV subtypes and prompt earlier treatment.
