Health Care Utilization and Pediatric Appendicitis: Insights From an Integrated Health System.
Article in The Permanente journal, 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
backgroundDisparities in pediatric appendicitis severity are associated with health care utilization. Identifying factors that influence the time to diagnosis may reveal opportunities to reduce the disparities. Health care utilization patterns and appendicitis outcomes were compared by neighborhood deprivation index within an integrated health care system to identify areas for intervention to improve pediatric appendicitis outcomes.
methodsThe authors conducted a multicenter retrospective cohort study of pediatric patients undergoing appendectomy between January 1, 2022, and June 30, 2023. Neighborhood deprivation index was categorized as less deprived (quintiles 1-3) or more deprived (quintiles 4-5). Primary outcomes were complicated vs simple appendicitis, hospital length of stay, and 30-day readmission. Secondary analyses examined prehospital health care utilization. Multivariable models assessed associations between neighborhood deprivation index, care patterns, and appendicitis severity.
resultsOf 1138 patients, 20% presented with complicated appendicitis. Patients from more-deprived neighborhoods (36.9%) had higher odds of complicated appendicitis (adjusted odds ratio [aOR], 1.6; 95% confidence interval [CI], 1.2-2.2). Prehospital health care utilization was low (12.6%) and more likely among patients from more-deprived than less-deprived neighborhoods (15% vs 11%;
conclusionModifiable health care delivery factors between the initial health care encounter and hospitalization represent potential areas for improving timely diagnosis and reducing disparities in pediatric appendicitis.
