Genomic origins and evolution of neo-sex chromosomes in Pacific Island birds.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The standard model of sex chromosome evolution is based on ancient XY or ZW systems. Young neo-sex chromosomes that form via the translocation of autosomal material to preexisting sex chromosomes provide materials to study early events in sex chromosome evolution. Neo-sex chromosomes are taxonomically widespread but, until recently, appeared to be rare in female-heterogametic taxa, including birds. Here, we report on the comparative evolutionary genomics of newly discovered neo-Z and neo-W sex chromosomes in two Pacific Island birds, the honeyeater species,
