Unique sex chromosome translocations and evolutionary strata in two Sylvioidea songbird families.
Article in BMC genomics, 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
Avian genomes are typically stable, yet instances of chromosome fissions, fusions and translocations are known across various lineages. For example, multiple sex chromosome translocations have been described in the superfamily Sylvioidea. In this study, we examine the sex chromosomes in two Sylvioidea families, Nicatoridae and Cisticolidae, using whole-genome data. We found sex-linkage of chromosomes Z and 4A, consistent with findings in other Sylvioidea species. We also identify sex-linkage of parts of chromosome 4, marking a novel discovery for Nicatoridae and a previously documented feature in Cisticolidae. These families are non-sister taxa, and the size of the translocated region of chromosome 4 differs between them, supporting independent translocation events. We uncover variation in recombination suppression and evolutionary strata on chromosome 4 between families, as well as between two genera within Cisticolidae. This study reveals both recurrent and independent trajectories in sex chromosome evolution, deepening our understanding of complex genomes.
