Exploring links between health and the genetic risk for smoking.
Article in SSM - population health, 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
Using the Health and Retirement Study (HRS), we document that among those aged 50-65, higher genetic scores for smoking are associated with worse health after accounting for detailed measures of smoking behavior and history. These associations are present even among those who report never smoking, suggesting they are not fully explained by smoking behavior. We then investigate several hypotheses for why this association persists. Parental and childhood characteristics-including parental smoking, parental risky behaviors, parental mortality, parental education, and childhood socioeconomic status-account for a modest portion of the observed association. We also examine behavioral and psychological characteristics linked to health. Higher genetic scores for smoking are associated with shorter financial planning horizons and lower optimism and conscientiousness, and these characteristics account for part of the observed association. Overall, our findings indicate that genetic scores for smoking may capture health-relevant heterogeneity that is not fully accounted for by observed smoking behavior.
