NON-CELIAC GLUTEN/WHEAT SENSITIVITY (NCG/WS). A BRAZILIAN CASES SERIES.

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
backgroundNon-celiac gluten/wheat sensitivity (NCGWS) is a varied disorder characterized by symptoms related to gluten intake, without celiac disease (CD) or wheat allergy. In Brazil, data on patients with NCGWS remain limited. Objectives: To describe the clinical, serological, and histopathological features of Brazilian patients diagnosed with NCGWS and to compare findings between sexes.
methodsA retrospective study was conducted using medical records of 36 patients diagnosed with NCGWS between 2015 and 2025 at a gastroenterology clinic in Curitiba, Brazil. Diagnosis was based on excluding CD and wheat allergy, clinical improvement after a gluten-free diet (GFD), and normal or Marsh I duodenal histology. Serology (anti-endomysium/anti-transglutaminase antibodies) and duodenal biopsies were analyzed. Symptoms, comorbidities, and demographic data were compared by sex.
resultsMost patients were women (83.3%). All had negative CD serology. Duodenal biopsies showed Marsh 0 (80% of females, 100% of males) or Marsh I changes. Gastrointestinal symptoms included flatulence, abdominal distension, and reflux; diarrhea was more common in males (P=0.0017). All patients reported symptom improvement after two months on a GFD.
conclusionIn this Brazilian cohort, NCGWS was more frequent in women. Accurate diagnosis relies on histological, serological, and especially thorough clinical evaluation. Multidisciplinary follow-up and personalized dietary guidance are vital for optimal patient outcomes.
