Disparities in MR enterography utilization stratified by social drivers of health (SDOH): a zip code-based analysis.
Article in Abdominal radiology (New York), 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
PURPOSE/
objectiveSocial drivers of health (SDOH) are nonmedical factors that influence health outcomes. We aim to evaluate if there are differences in MR enterography (MRE) utilization among the various zip codes surrounding UMass Memorial Medical Center in Worcester, MA stratified by various SDOH. MATERIALS AND
methodsIn this HIPAA compliant IRB approved retrospective population-based study, MRE utilization for patient zip codes within a 10 mile radius of UMass Memorial Medical Center was determined by dividing the number of MREs performed from 01/08/2018 to 07/27/2022 by the population for each zip code. Data on median household income (MHI), population in poverty (PIP), health insurance status, race and ethnicity, and transportation access was collected from the United Census Bureau and data on social vulnerability index (SVI) was collected from the Centers of Disease Control for each zip code. Disadvantaged zip codes for each SDOH were defined as zip codes in the bottom quartile for MHI and the top quartile for the remaining SDOH. MRE utilization was compared between the two groups for each SDOH by one-way analysis.
resultsThe mean MRE utilization for the included zip codes was 1.1 MRE per 1000 capita over the study period of 55 months. The MRE utilization was lower for the disadvantaged zip codes stratified by each studied SDOH. The largest difference in MRE utilization was identified between disadvantaged zip codes and non-disadvantaged zip codes stratified by SVI and percentage of population without a car, at 0.5 MRI per 1000 capita.
conclusionIndividuals living in disadvantaged areas have lower rates of MRE utilization, which is commonly used in the evaluation of inflammatory bowel disease (IBD). Disparate utilization of MRE could lead to disparities in outcome for those with IBD.
