Lupus Erythematosus Tumidus in the Differential Diagnosis of Facial Erythema.
Article in Cureus, 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
Lupus erythematosus is an autoimmune disease that frequently presents with dermatologic manifestations. When it is limited to the facial area, it is difficult to distinguish from other inflammatory diseases. Among the differential diagnoses of facial erythema, lupus erythematosus tumidus (LET) is an uncommon entity that represents a subtype of lupus erythematosus. It is characterized as a photosensitive dermatosis with a favorable clinical course and prognosis. A 32-year-old female patient presented with dermatosis localized to the face, specifically in the frontal and maxillary regions, characterized by persistent facial erythema with papular eruptions over a two-year period. Initially diagnosed as rosacea, she received multiple treatments without clinical improvement. Subsequently, histopathological findings led to the diagnosis of LET, a form of intermittent cutaneous lupus erythematosus that occurs much less frequently than other forms of cutaneous lupus. It presents with a relapsing course associated with sun exposure, histopathologically characterized by superficial and deep perivascular and periadnexal lymphocytic infiltrates with dermal mucin deposition. It may clinically mimic other skin disorders. Therefore, skin biopsies are indicated in various clinical scenarios when histopathologic information is required to make a diagnosis and establish the definitive treatment plan.
