Coded Gastrointestinal Diagnoses in Women Aged 18-44 Years with Iron Deficiency Anemia Without Selected Coded Alarm Features Who Underwent Same-Day Bidirectional Endoscopy: A Multicenter U.S. Electronic Health Record Study.
Article in Digestive diseases and sciences, 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
backgroundThe role of bidirectional endoscopy in younger women with iron deficiency anemia (IDA) and no alarm features remains uncertain.
aimsTo describe gastrointestinal (GI) codes recorded through 3 months after same-day bidirectional endoscopy in women aged 18-44 years with biochemically supported IDA and without selected coded alarm features.
methodsWe conducted a retrospective descriptive TriNetX study. The first colonoscopy defined index; esophagogastroduodenoscopy was required the same day. An IDA code, hemoglobin ≤12 g/dL, and ferritin ≤45 ng/mL were required within 3 months on or before index. Outcomes were codes recorded from index through 3 months afterward. A sensitivity analysis excluded prior colorectal malignancy and inflammatory bowel disease (IBD) codes.
resultsThe cohort included 769 women from 57 organizations (mean age, 37 [SD, 6] years); the condition-specific denominator was 768. Common upper-GI codes were gastritis/duodenitis (343/768, 44.7%), hiatal hernia (84/768, 10.9%), Helicobacter pylori (78/768, 10.2%), and gastric/duodenal ulcer (48/768, 6.3%); no upper-GI malignancy code was recorded. Lower-GI codes included hemorrhoids (246/768, 32.0%), D12-coded benign colorectal/anal neoplasm (93/768, 12.1%), and IBD (67/768, 8.7%). The colorectal malignancy code count was privacy suppressed (1-10/768; ≤1.3%). After excluding prior IBD codes, 13/710 (1.8%) had an IBD code recorded.
conclusionsThese coded diagnoses cannot be assumed to represent newly detected lesions or causes of IDA. Without a non-endoscoped comparison group, the study cannot establish the benefit of routine or selective endoscopy.
