Health Literacy and Awareness of Family Health History in the All of Us Research Program.
Article in Public health genomics, 2026. 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
introductionA 2016 study showed that limited health literacy was associated with lower awareness of family health history. However, this analysis was conducted among adult patients in St. Louis, Missouri, thereby warranting broader replication.
methodsWe quantified the association between health literacy and awareness of family health history using a nationwide cross-sectional study of 286,293 All of Us Research Program participants. Modified Poisson regression models estimated PRs (PRs): model 1 (unadjusted), model 2 (demographic factors), model 3 (socioeconomic status), model 4 (health insurance), model 5 (self-rated health status), and model 6 (number of chronic health conditions).
resultsThe average age was 53 years (SD = 17), with 4% who self-reported no awareness of family health history and 17% who had limited health literacy. Without controlling for confounders (model 1), participants with limited health literacy were 3.06 (95% confidence interval [CI]: 2.95-3.17) times more likely than those with adequate health literacy to report no awareness of family health history. This significant association persisted but attenuated in models 2 (adjusted PR [aPR]: 2.04, 95% CI: 1.96-2.12) and 3 (aPR: 1.43, 95% CI: 1.37-1.49). The association remained stable in models 4-6 with the sequential addition of health insurance coverage (aPR: 1.42, 95% CI: 1.37-1.48), self-rated health status (aPR: 1.42, 95% CI: 1.36-1.47), and number of chronic health conditions (aPR: 1.42, 95% CI: 1.36-1.48).
conclusionThese findings indicate that increasing health literacy may increase awareness of family health history, which is vital for delivery of personalized healthcare and active patient participation in precision medicine.
