Acute Urticaria as the Sole Manifestation of Dengue Fever: A Rare Case Report.
Article in Clinical case reports, 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
Urticaria is a very uncommon dermatological manifestation of infection by the dengue virus. It can hinder diagnosis since some of its features overlap with allergic conditions, such as maculopapular and petechial rashes. We present a case of a 32-year-old male, resident of a dengue-endemic area, who presented with an acute onset of generalized pruritic wheals and angioedema in the absence of any systemic symptoms, including fever. Laboratory tests showed leukopenia, thrombocytopenia, and elevated liver enzymes. Dengue serology confirmed primary infection (NS1 antigen and IgM positive). The patient responded to antihistamines and supportive care without complications. This case highlights the need to consider dengue in the differential diagnosis of acute urticaria in endemic areas, even without typical systemic symptoms.
