APOE genotype and cognitive decline: educational context as a moderator of genetic risk.
Article in The journals of gerontology. Series B, Psychological sciences and social sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivesThe apolipoprotein E (APOE) ε4 allele is linked to increased risk of Alzheimer's disease and cognitive decline. While educational attainment appears to mitigate this risk, it is not a direct measure of the early-life environment. This study examined whether childhood exposure to well- versus poorly resourced educational contexts modified the association between APOE ε4 and cognitive decline, independent of parent and respondent educational attainment.
methodsWe used data from the Health and Retirement Study (2006-2018) linked with state-level data on public education systems. The sample included U.S.-born respondents who participated in the 2006-2012 genetic data collection, lived in one of the 48 contiguous states at age 10, and were born between 1914 and 1959 (n = 14,817 respondents, 76,806 person-period observations). To measure educational context, we created a standardized factor score representing state education resources, derived from indicators such as per-pupil spending, pupil-teacher ratios, and teacher salary. We used mixed effects models to estimate the interaction between APOE ε4 and state education resources, adjusting for parent and respondent education (measured in years of schooling).
resultsAPOE ε4 carriers who grew up in states with low education resources experienced an accelerated rate of cognitive decline compared to carriers from states with high education resources. For noncarriers, the rate of cognitive decline was not statistically different across educational contexts. DISCUSSION: Ensuring access to high-quality education may serve as an effective social policy to slow cognitive decline among future cohorts of older adults at high genetic risk of dementia.
