The Role of Race/Ethnicity on the Association between Neighborhood Deprivation and Breast Cancer Outcomes among Kentucky Patients with Breast Cancer (2010-2022).

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
backgroundKentucky is within the top five leading states for breast cancer mortality nationwide. This study investigates the association between neighborhood socioeconomic disadvantage and breast cancer outcomes, including surgical treatment, radiotherapy, chemotherapy, and survival, and how associations vary by race and ethnicity in Kentucky.
methodsWe conducted a retrospective cohort analysis using data from the Kentucky Cancer Registry for patients with breast cancer diagnosed between 2010 and 2017, with follow-up through December 31, 2022. We linked Kentucky Cancer Registry data with census tract data to examine the relationship between area deprivation index (ADI) and breast cancer outcomes. Logistic regression and Cox proportional hazards models analyzed binary outcomes and time-to-event data, respectively.
resultsWomen in the most disadvantaged (ADI fourth quartile) neighborhoods were more likely to be diagnosed at later stages (OR, 1.26; 95% confidence interval, 1.12-1.41) and 34% more likely to die from breast cancer (HR, 1.34; 95% confidence interval, 1.14-1.57) after adjusting for age, race, tobacco use, tobacco pack-years, marital status, insurance status, family history, stage at diagnosis, breast cancer subtype, and residence in Appalachia when compared with women living in the least disadvantaged neighborhoods (ADI first quartile).
conclusionsWomen in disadvantaged neighborhoods had significantly higher odds of late-stage diagnosis and breast cancer death, regardless of race, indicating that neighborhood factors contribute to breast cancer disparities. IMPACT: Socioeconomic and neighborhood factors may contribute to breast cancer outcomes, suggesting the necessity for targeted interventions. Future research should explore the effectiveness of such interventions and investigate additional social determinants contributing to disparities.
