Protein markers of synaptic behavior and chromatin remodeling of the neo-XY body in phyllostomid bats.
Article in Chromosoma, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 XX/XY system is the rule among mammals. However, many exceptions from this general pattern have been discovered since the last decades. One of these non-conventional sex chromosome mechanisms is the multiple sex chromosome system, which is evolutionary fixed among many bat species of the family Phyllostomidae, and has arisen by a translocation between one original gonosome (X or Y chromosome), and an autosome, giving rise to a "neo-XY body." The aim of this work is to study the synaptic behavior and the chromatin remodeling of multiple sex chromosomes in different species of phyllostomid bats using electron microscopy and molecular markers. Testicular tissues from adult males of the species Artibeus lituratus, Artibeus planirostris, Uroderma bilobatum, and Vampyrodes caraccioli from the eastern Amazonia were analyzed by optical/electron microscopy and immunofluorescence of meiotic proteins involved in synapsis (SYCP3 and SYCE3), sister-chromatid cohesion (SMC3), and chromatin silencing (BRCA1, γ-H2AX, and RNApol 2). The presence of asynaptic axes-labeled by BRCA1 and γ-H2AX-at meiotic prophase in testes that have a normal development of spermatogenesis, suggests that the basic mechanism that arrests spreading of transcriptional silencing (meiotic sex chromosome inactivation (MSCI)) to the autosomal segments may be per se the formation of a functional synaptonemal complex between homologous or non-homologous regions, and thus, this SC barrier might be probably related to the preservation of fertility in these systems.
