1 · What the graph read from it

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.

2 · The registry

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

Techniques such as whole chromosome painting (WCP) have effectively expanded our understanding of the evolution and organization of the genome in fish, allowing us to obtain more detailed information about several evolutionary questions. The genus Gymnotus is the most cytogenetically studied among the Gymnotiformes, having a significant karyotypic diversity. Molecular cytogenetic studies in the genus Gymnotus show a dynamic reorganization in the karyotype, in addition to the presence of different sex chromosome systems. In this study, with whole chromosome probes from the karyotype of Gymnotus carapo orientalis sensu stricto cytotype 2n = 42, we analyzed the karyotype of Gymnotus mamiraua 2n = 54, from two localities, and compared with previous studies, to obtain a better understanding of the homologies and chromosomal differences among the species of this genus. The results shows both populations with no difference detected by chromosome painting, and overall, a larger number of signals were observed with the fluorescent probes, since GMA has a higher diploid number. Using chromosomal painting on a greater number of species will make it possible to construct a map of homologies between them that will help define the phylogeny of the group.
