Chilblains With Tumid Lupus Features in a Patient With Sjögren's Syndrome: A Case Report.
Article in Cureus, 2025. 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
Sjögren's syndrome is an autoimmune disorder characterized by lymphocytic infiltration of exocrine glands, primarily affecting the lacrimal and salivary glands, resulting in dry eyes and mouth. We report a case of a 22-year-old female with Sjögren's syndrome (diagnosed at age 14), who developed chilblain-like lesions with histopathological features of tumid lupus. The patient presented with low-grade fever and painful erythematous papules on the fingers, toes, ears, face, and trunk. Serological workup revealed multiple autoantibodies (anti-SSA (Sjögren's-syndrome-related antigen A), anti-SSB (Sjögren's-syndrome-related antigen B), anti-centromere, anti-U1RNP (anti-U1 ribonucleoprotein), ANA (antinuclear antibody), and rheumatoid factor). Skin biopsy demonstrated interface dermatitis with lymphoplasmacytic infiltration and increased dermal mucin. After an inadequate response to conventional therapy (hydroxychloroquine, methotrexate, prednisone, and topical treatments), the patient showed significant improvement with belimumab. This case highlights the overlap between Sjögren's syndrome and lupus spectrum disorders. It demonstrates the potential efficacy of B-cell-targeted therapy in managing refractory cutaneous manifestations of autoimmune overlap syndromes.
