Quantitative dissection of sexual dimorphism in mice through Y-linked gene knockouts and multivariate phenotyping.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Sexual dimorphism (SDM) is regulated by sex chromosomes, yet the specific contribution of individual genes remains unclear. To address this, we conducted a comprehensive phenotyping analysis to investigate the roles of Y chromosome-linked genes in SDM formation in mice. Using C57BL/6J mice, we identified 49 SDM traits across 14 biological systems. To assess gene-specific effects, we generated knockout (KO) mice for 10 unique Y-linked genes using CRISPR/Cas9. As expected, Sry KO resulted in feminization of most SDM traits, including gonadal sex. However, certain body size-related traits remained male-like, suggesting the involvement of additional Y-linked genes. Consistently, KOs of Uty and Usp9y significantly altered traits related to body and organ size. We further applied a dimensionality reduction approach to quantitatively capture SDM variation at the individual level, enabling visualization of phenotypic shifts in each KO mouse. Our findings demonstrate that non-Sry Y-linked genes contribute to SDM and introduce a generalizable framework for quantifying sex differences across individuals and species.
