Family SES amplifies genetic influences on organized activity involvement from childhood to young adulthood: evidence from the German twin family panel.
Article in Frontiers in sociology, 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
Organized activity involvement contributes to social cohesion and individual development, yet substantial socioeconomic disparities persist. Although prior research shows that both genetic differences and family socioeconomic status (SES) shape organized activity involvement, less is known about how socioeconomic contexts condition the realization of genetic potential. Drawing on gene-environment interaction theory, this study examines whether family SES amplifies or attenuates genetic influences on organized activity involvement. We contrast two competing perspectives: the High-SES Amplification model, which predicts stronger genetic influences in advantaged contexts, and the Low-SES Expression model, which predicts stronger genetic influences in disadvantaged contexts. Using data from the German Twin Family Panel (TwinLife, ages 4-25,
