Cytogenetic evidences of genome rearrangement and differential epigenetic chromatin modification in the sea lamprey (Petromyzon marinus).
Article in Genetica, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
This work explores both the chromatin loss and the differential genome methylation in the sea lamprey (Petromyzon marinus) from a molecular cytogenetic point of view. Fluorescent in situ hybridization experiments on meiotic bivalents and mitotic chromosomes corroborate the chromatin loss previously observed during the development of the sea lamprey and demonstrate that the elimination affects not only to Germ1 sequences but also to the rpt200 satellite DNA and most part of the major ribosomal DNA present on the germinal line. 5-Methylcytosine immunolocation revealed that the GC-rich heterochromatin is highly methylated in the germ line but significantly less in somatic chromosomes. These findings not only support previous observations about genome rearrangements but also give new information about epigenetic changes in P. marinus. The key position of lampreys in the vertebrate phylogenetic tree makes them an interesting taxon to provide relevant information about genome evolution in vertebrates.
