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
The clinical data of 4 pediatric patients with collagenous gastritis (CG) diagnosed at the Department of Pediatrics of Peking University Third Hospital between January 2021 and October 2025 were retrospectively analyzed. The median age at onset was 10.8 years. All patients presented with iron-deficiency anemia, and two also experienced abdominal pain. Gastroscopy in all cases revealed a nodular gastric mucosal appearance. Histopathological examination confirmed subepithelial collagen band thickness greater than 10 μm in all patients, with varied patterns of inflammatory infiltrate, including two cases with eosinophil-predominant inflammation and one with lymphocytic gastritis. Two patients were found to have collagenous duodenitis, while none showed collagenous colitis. Serological testing identified one patient with low-titer positive antinuclear antibodies and another with elevated gastrin-17 levels. Treatment consisted of iron supplementation in all cases, combined with gastric mucosal protectants in three patients and glucocorticoid therapy in one patient. Follow-up of three patients showed clinical improvement with resolution of anemia, and two also demonstrated histological improvement with reduced gastric inflammation and collagen deposition. Pediatric CG is characterized primarily by iron-deficiency anemia and nodular gastric mucosal changes, accompanied by duodenal involvement in some patients. These findings underline the importance of a comprehensive evaluation of the entire gastrointestinal tract. Diagnosis relies on distinct endoscopic and pathological features, while attention should also be paid to potential biomarkers. A combined treatment approach, including iron supplementation, mucosal protection, and glucocorticoids when necessary, may lead to clinical and histological remission.
