Comparison of the Initial Loco-Regional Treatment Received for Early-Stage Breast Cancer between Elderly Women in Appalachia and a United States - Based Population: Good and Bad News.
Article in Global journal of breast cancer research. 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
backgroundBreast conserving surgery (BCS) followed by radiation therapy (RT) (BCS+RT) is as effective for long-term survival of invasive early-stage breast cancer (ESBC) as mastectomy, and is the local treatment option selected by the majority of women with ESBC. Women of older age and vulnerable socio-demographic characteristics are at greater risk for receiving substandard (BCS only) and non-preferred treatments (mastectomy), such as populations of women from the Appalachian region of United States.
methodsUsing a retrospective cohort study design, we identified 26,106 patients from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked dataset and 811 patients from the West Virginia Cancer Registry (WVCR)-Medicare dataset age ≥ 66 diagnosed from 2003 to 2006 with stage I-II breast cancer. Multivariable logistic regression models estimated type of initial treatment received between WVCR-Medicare and SEER-Medicare patients, and the association with type of treatment.
resultsOverall, women in WV were 0.82 (95% CI 0.68-0.99) and 0.70 (95% CI 0.58-0.84) times less likely to have mastectomy or BCS only vs. BCS+RT, than those in SEER regions. Women in WV of increasing age, greater comorbidity, stage II disease, and non-white race were more likely to have mastectomy or BCS only vs. BCS+RT, whereas, those residing in areas of higher income, higher education, and metro status were less likely, than similarly characterized women from SEER regions.
conclusionsFindings from this study suggest that the magnitude of disparities in breast cancer treatment between groups of women with more and less resources are even greater in the Appalachian region, than they are among US populations. Improving access to oncology treatment services, as well as, the implementation of patient navigation programs are needed to improve patterns of initial treatment for ESBC among at-risk populations.
