Speciation by hybridization: the mind-boggling nature, educational, and research value of the largest group of unisexual vertebrates.
Article in Bioscience, 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
Thirteen species of North American lizards are remarkable because only females exist, which reproduce by cloning unfertilized eggs. Their closest relatives reproduce sexually, with eggs fertilized by sperm from males, as in most vertebrates. The unisexual species originated through hybridization, dispensing with sex and males in a single generation. These lizards hold tremendous potential in science education as a fascinating model for learning about fundamental biological concepts, and in research for developing knowledge with medical applications for reproductive biology, embryonic development, and genetic interactions. These lizards maintain genome integrity in a hybrid state in which recombination is absent, but do not suffer from conditions or disorders such as Down's Syndrome or cancer that are caused by aneuploidy in humans. The multifarious impacts of hybridization on the diversity of species in this group present an exceptional opportunity to deepen understanding of the complicated process of evolutionary diversification.
