Geographic Disparities in the Supply and Demand of Gastroenterologists Across the United States: Forecasting a National Shortage.
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. Cited by 7 papers.
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
purposeThere is a lack of contemporary research on the supply and demand of gastroenterologists in the United States (US). We hypothesized that significant differences in gastroenterologist workforce adequacy would exist across the US especially in non-metropolitan areas and certain identifiable states.
methodsWe conducted a cross-sectional study of gastroenterologists with the Health Workforce Simulation Model. Adequacy was defined as the ratio of supply over demand for gastroenterologists, which was assessed from 2025 to 2037. Chi-squared tests were used to compare gastroenterologist workforce adequacy by geography.
resultsIn 2025, non-metropolitan areas had lower gastroenterologist adequacy than metropolitan areas (29.7% vs 106%, P < 0.001). Regionally, the South had the lowest gastroenterologist adequacy and the Northeast had the highest (87% vs 134%, P < 0.001). By 2037, non-metropolitan areas were projected to have lower gastroenterologist adequacy than metropolitan areas (29.4% vs 102%, P < 0.001). The South was projected to have the lowest gastroenterologist adequacy compared to the Northeast, which had the highest (80% vs 133%, P < 0.001). By 2037, the states with the lowest gastroenterologist adequacy were Nevada (43.5%), Alaska (50.0%), and Idaho (53.3%).
conclusionShortages are anticipated for US gastroenterologists, which are greatest in non-metropolitan areas and certain identified states. Additional strategies are needed to increase the supply of gastroenterologists in areas with identified deficiencies.
