Can a Y Chromosome Degenerate in an Evolutionary Instant? A Commentary on Fong et al. 2023.
Article in Genome biology and evolution, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
It is well known that the Y chromosomes of Drosophila and mammals and the W chromosomes of birds carry only small fractions of the genes carried by the homologous X or Z chromosomes, and this "genetic degeneration" is associated with loss of recombination between the sex chromosome pair. However, it is still not known how much evolutionary time is needed to reach such nearly complete degeneration. The XY pair of species in a group of closely related poecilid fish is homologous but has been found to have either nondegenerated or completely degenerated Y chromosomes. We evaluate evidence described in a recent paper and show that the available data cast doubt on the view that degeneration has been extraordinarily rapid in the latter (Micropoecilia species).
