Short-and Long-term Patient Outcomes in Hospitals Primarily Serving Patients with Colorectal Cancer from High-Poverty Areas-An Observational Cohort Study.
Observational study in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPrior evidence indicate that differences in treatment settings between patients with colorectal cancer (CRC) from high-poverty areas (HPA, ≥ 20% residents living under poverty level) and low-poverty areas (LPA) might have contributed to disparities in their health outcomes. We sought to determine whether certain hospitals predominantly provided surgical care for patients with CRC from HPAs and examine associated patient outcomes. PATIENTS AND
methodsWe identified patients undergoing surgery for nonmetastatic CRC diagnosed during 1/1/2009-12/31/2019 from SEER-Medicare. We defined poverty-area-serving (PAS) hospitals as hospitals with ≥ 50% patients from HPAs. We compared in-hospital adverse events, 30 day readmission, and long-term mortality between patients from HPAs and LPAs treated at PAS and non-PAS hospitals using logistic and Cox regression.
resultsOur cohort included 81,992 patients with CRC (median age = 78 years, 53.8% female, 15.9% in HPAs) treated by 991 hospitals. The 180 (18.2%) PAS hospitals treated 64.2% of patients from HPAs versus 2.6% from LPAs. Compared with patients from LPAs treated at non-PAS hospitals, patients from HPAs treated at PAS hospitals had more frequent in-hospital adverse events (OR[95%CI] = 1.17[1.07-1.29]), 30-day readmission (OR[95%CI] = 1.33[1.20-1.47]), worse all-cause (HR[95%CI] = 1.16[1.10-1.22]), and cancer-specific mortality (HR[95%CI] = 1.23[1.15-1.32]).
conclusionsA group of PAS hospitals treated a significant proportion of patients with CRC from HPAs and few from LPAs and was associated with worse short- and long-term patient outcomes. These findings highlight the presence and negative impact of healthcare segregation by area-level poverty and systemic inequities faced by individuals from HPAs. Multilevel resources are needed to address quality of care and other healthcare-associated needs for individuals from disadvantaged areas.
