The relationship of neighborhood socioeconomic disadvantage and pretreatment cancer-related cognitive impairment in women with breast cancer: A post hoc analysis of a randomized controlled trial.
Trial report in Cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02793921 (Influence of Exercise on Neurocognitive Function in Breast Cancer), which is not on this 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.

Abstract
backgroundUp to 30% of women with breast cancer experience cancer-related cognitive impairment (CRCI) even before they receive treatment. The authors conducted a post hoc analysis to examine the relationship between neighborhood socioeconomic disadvantage and CRCI in treatment-naive postmenopausal women with early stage breast cancer.
methodsThe Exercise Program in Cancer and Cognition was a single-blind, 6-month, randomized controlled trial evaluating moderate-intensity aerobic exercise versus usual activity on neurocognitive function. By using baseline data from treatment-naive participants (n = 100), neighborhood socioeconomic disadvantage was assessed using the Area Deprivation Index (national percentile). Cognitive function was measured using composite domain scores. Associations were examined using correlation and linear regression analyses, adjusting for potential covariates/confounders.
resultsOn average, participants were aged 63 years and had 16 years of education. Greater neighborhood disadvantage was associated with poorer cognitive function in domains of verbal memory (p = .032), working memory (p = .043), mental flexibility (p = .049), and processing speed (p = .026). In adjusted analyses, working memory remained associated with the Area Deprivation Index (p = .019) with adjustment for age; however, associations with the Area Deprivation Index were attenuated for verbal memory after adjustment for education (p = .067), for mental flexibility after adjustment for depressive symptoms (p = .175), and for processing speed after adjustment for age and body mass index (p = .065).
conclusionsNeighborhood socioeconomic disadvantage may contribute to cognitive vulnerability before cancer treatment. However, these findings suggest that years of education and depressive symptoms should be factored into the consideration of neighborhood-level factors when assessing CRCI risk among women with breast cancer (Clinicaltrials.gov identifier NCT02793921).
