Mitochondrial and chromosomal insights into karyotypic evolution of the pygmy mouse, Mus minutoides, in South Africa.

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 African pygmy mouse, Mus minutoides, displays extensive Robertsonian (Rb) diversity. The two extremes of the karyotypic range are found in South Africa, with populations carrying 2n = 34 and 2n = 18. In order to reconstruct the scenario of chromosomal evolution of M. minutoides and test the performance of Rb fusions in resolving fine-scale phylogenetic relationships, we first describe new karyotypes, and then perform phylogenetic analyses by two independent methods, using respectively mitochondrial cytochrome b sequences and chromosomal rearrangements as markers. The molecular and chromosomal phylogenies were in perfect congruence, providing strong confidence both for the tree topology and the chronology of chromosomal rearrangements. The analysis supports a division of South African specimens into two clades showing opposite trends of chromosomal evolution, one containing all specimens with 34 chromosomes (karyotypic stasis) and the other grouping all mice with 18 chromosomes that have further diversified by the fixation of different Rb fusions (extensive karyotypic reshuffling). The results confirm that Rb fusions are by far the predominant rearrangement in M. minutoides but strongly suggest that recurrent whole-arm reciprocal translocations have also shaped this genome.
