Genetic prediction of early adolescent chronotype: effects of sex and pubertal status.
Article in Sleep, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
STUDY
objectivesAdolescence is characterized by later sleep onset and wake times, indicating a shift to an evening chronotype. Genome-wide association studies (GWAS) in adults show chronotype is polygenic and causally linked to depression, schizophrenia, and cognitive function. Yet, the impact of genetics on adolescent chronotype remains largely unexplored, and biological factors influencing the predictive relationship between genetics and chronotype have not been well-defined. This study aims to assess the utility of polygenic scores (PGS) derived from adult GWAS in predicting adolescent chronotype, mental health, and cognition while considering sex- and puberty-dependent effects.
methodsGeneralized linear models were used to assess the relationship between PGS for chronotype and self-reported chronotype, mental health, and cognition in 2411 youths of European ancestry aged 10-13 years. Interaction terms assessed whether the genotype-phenotype relationships varied by sex or pubertal development. Statistical significance was determined using a likelihood ratio test.
resultsSignificant sex- and puberty-dependent effects were observed. Higher PGS for morningness concordantly predicted earlier self-reported chronotype, but in female youth only. Follow-up analyses showed that sex-specific effects were mediated by the interaction between PGS and pubertal status. Greater genetic predisposition for morningness was negatively associated with somnolence and cognition in males and negatively associated with psychotic-like experiences in females.
conclusionsThe influence of genetic predisposition for early versus late chronotype on adolescent sleep-wake behavior emerges as puberty progresses. These findings suggest puberty is a critical transition when genetic variants associated with chronotype in adults become relevant to pediatric cohorts.
