Hydroxychloroquine-induced Sweet's Syndrome: A Case Report and Literature Review.
Review in Acta dermato-venereologica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Sweet's syndrome (or acute febrile dermatosis) is a neutrophilic dermatosis with a characteristic presentation encompassing specific clinical (fever and erythemato-violaceous oedematous papules, plaques and nodules), laboratory (neutrophilia and increased inflammatory markers), and histological (dermal neutrophilic infiltrate without vasculitis) features. Its pathophysiology is poorly understood but there seems to be an auto-inflammatory component related to mutations in inflammasome genes. It has been subdivided into its classic form, malignancy-associated, and drug-induced, according to its aetiology. The condition usually responds rapidly to steroid therapy, but recurrences are common. This report presents an extremely rare case of hydroxychloroquine-induced Sweet's syndrome, plus a review of the literature, which encompasses 3 previous cases of Sweet's syndrome induced by hydroxychloroquine and 1 induced by chloroquine. Despite being relatively easy to diagnose, aetiological investigation poses challenges to the clinician, especially in the elderly population, as several confounding factors might be present. Further studies are necessary to shed light on the pathophysiology behind this entity, to further facilitate diagnostic workup and treatment strategies.
