Isolated colonic strongyloidiasis presenting as iron deficiency anemia with negative duodenal biopsies and stool studies.
Article in IDCases, 2026. 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
Background: Case presentation: A 67-year-old man with longstanding iron deficiency anemia presented with fatigue and intermittent eosinophilia. Upper endoscopy with duodenal biopsies was unrevealing. Colonoscopy demonstrated diffuse polypoid lesions with surrounding erythema and edema throughout the colon. Histopathologic examination of colonic biopsies revealed invasive Conclusion: This case highlights a rare presentation of isolated colonic strongyloidiasis causing chronic iron deficiency anemia. Negative stool studies and unrevealing duodenal biopsies did not exclude infection, with diagnosis established only through colonic histopathology. Strongyloidiasis should be considered in patients with unexplained eosinophilia, iron deficiency anemia, or eosinophilic colitis despite negative stool studies and unrevealing upper gastrointestinal biopsies.
