Pegasoferae, an unexpected mammalian clade revealed by tracking ancient retroposon insertions.

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
Despite the recent large-scale efforts dedicated to comprehensive phylogenetic analyses using mitochondrial and nuclear DNA sequences, several relationships among mammalian orders remain controversial. Here, we present an extensive application of retroposon (L1) insertion analysis to the phylogenetic relationships among almost all mammalian orders. In addition to demonstrating the validity of Glires, Euarchontoglires, Laurasiatheria, and Boreoeutheria, we demonstrate an interordinal clade that links Chiroptera, Carnivora, and Perissodactyla within Laurasiatheria. Re-examination of a large DNA sequence data set yielded results consistent with our conclusion. We propose a superordinal name "Pegasoferae" for this clade of Chiroptera + Perissodactyla + Carnivora + Pholidota. The presence of a single incongruent L1 locus generates a tree in which the group of Carnivora + Perissodactyla associates with Cetartiodactyla but not with Chiroptera. This result suggests that incomplete lineage sorting of an ancestral dimorphism occurred with regard to the presence or absence of retroposon alleles in a common ancestor of Scrotifera (Pegasoferae + Cetartiodactyla), which was followed by rapid divergence into the extant orders over an evolutionarily short period. Accordingly, Euungulata (Cetartiodactyla + Perissodactyla) and Fereuungulata (Carnivora + Pholidota + Perissodactyla + Cetartiodactyla) cannot be validated as natural groups. The interordinal mammalian relationships presented here provide a cornerstone for future studies in the reconstruction of mammalian classifications, including extinct species, on evolution of large genomic sequences and structure, and in developmental analysis of morphological diversification.
