Cross-sectional Study of Dermatitis Herpetiformis with Focus on Neurological Comorbidities.

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
Dermatitis herpetiformis (DH) is a chronic autoimmune blistering skin disease strongly associated with coeliac disease. This cross-sectional study investigated the clinical, serological, and neurological characteristics of 114 DH patients (70 males, 44 females; mean age: 50.2 years; 13 newly, 101 previously diagnosed) at Semmelweis University, Budapest, between 2020 and 2023. Diagnosis was confirmed by direct immunofluorescence microscopy. Serum autoantibodies against transglutaminase 2 (TG2), 3 (TG3), and 6 (TG6) were quantified using immunoassays. While at the time of evaluation, 65.8% of patients adhered to a strict gluten-free diet (GFD), 34.2% followed an incomplete or no GFD. Autoantibodies against TG2 and TG3 were each detected in 24.6% of patients, while TG6 autoantibodies were detected in 53.5%. Neurological comorbidities were reported in 43.9%, with headache and radiculopathy being the most prevalent. Hashimoto's thyroiditis was present in 19.3%, and anaemia in 32.5% of patients. These findings, derived from a globally relevant patient cohort, underscore the systemic nature of DH and its strong association with transglutaminase autoimmunity, neurological and autoimmune comorbidities, emphasizing the need for early diagnosis, strict adherence to a GFD, and a multidisciplinary approach to optimize patient outcomes.
