Comparative genomic analysis links karyotypic evolution with genomic evolution in the Indian muntjac (Muntiacus muntjak vaginalis).
Article in Chromosoma, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The karyotype of Indian muntjacs (Muntiacus muntjak vaginalis) has been greatly shaped by chromosomal fusion, which leads to its lowest diploid number among the extant known mammals. We present, here, comparative results based on draft sequences of 37 bacterial artificial clones (BAC) clones selected by chromosome painting for this special muntjac species. Sequence comparison on these BAC clones uncovered sequence syntenic relationships between the muntjac genome and those of other mammals. We found that the muntjac genome has peculiar features with respect to intron size and evolutionary rates of genes. Inspection of more than 80 pairs of orthologous introns from 15 genes reveals a significant reduction in intron size in the Indian muntjac compared to that of human, mouse, and dog. Evolutionary analysis using 19 genes indicates that the muntjac genes have evolved rapidly compared to other mammals. In addition, we identified and characterized sequence composition of the first BAC clone containing a chromosomal fusion site. Our results shed new light on the genome architecture of the Indian muntjac and suggest that chromosomal rearrangements have been accompanied by other salient genomic changes.
