Examining the heritability of actigraphy-assessed and parent-reported sleep duration in a community sample of twins across childhood and adolescence.
Article in Sleep medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Meta-analytic evidence indicates that the heritability of sleep duration increases across infancy and childhood, and peaks in adolescence, however, relatively few genetically-informed studies have examined sleep duration longitudinally across development, and estimates vary substantially by reporter and method of assessment. Extending on prior published heritability estimates from the Arizona Twin Project in infancy and middle childhood, the present study examines new data from the 8-, 9-, 10-, 11-, and 13-year waves (Ns = 388-739 twins; monozygotic = 29.1%-32.6%, same-sex dizygotic = 33.4%-38.8%, opposite-sex dizygotic = 31.5%-34.6%). Parents reported on twins' sleep at each wave. Twins wore wrist-based accelerometers for approximately one week at ages 8, 10, and 13. Univariate models indicated that the heritability of parent-report increased across middle childhood and early adolescence, and shared environmental influences decreased (h
