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
aimsThe aim is to assess the usefulness of routine duodenal biopsy in patients presenting with iron deficiency anemia in areas with low prevalence of celiac disease (CD).
methodsThis prospective study included 156 patients with unexplained iron deficiency anemia, referred to the Department of Gastroenterology. JSS Medical College and Hospital, Mysuru, India. All patients underwent upper gastrointestinal (GI) endoscopy and duodenal biopsy. Histopathological changes were assessed according to the Marsh classification. Celiac disease was defined as having Marsh II or above on histopathology or being seropositive with Marsh I histopathology and having a good response to gluten-free diet. Furthermore, patients were evaluated for Immunoglobulin A (IgA) anti-tissue transglutaminase (t-TG) antibody with enzyme-linked immunosorbent assay technique.
resultsOne hundred and fifty-six patients were included in the study with a mean age of 52.17 ± 16.01 (67.7% of females) who underwent endoscopic duodenal biopsy. Three (1.9%) were diagnosed to have CD on biopsy, which was confirmed with a serological test (IgA Anti t-Tg). Positivity for CD did not correlate with the severity of anemia or GI symptoms.
conclusionsCeliac disease should be considered in patients presenting with unexplained iron deficiency anemia, even if not accompanied by GI symptoms. Doing initial serological testing followed by duodenal biopsy may be an appropriate approach, especially in areas with a low prevalence of celiac disease. Routine duodenal biopsies did not seem a reasonable approach considering cost-effectiveness and its clinical utility.
