Distribution pattern of histone H3 phosphorylation at serine 10 during mitosis and meiosis in Brachiaria species.
Article in Journal of genetics, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Histones are the major eukaryotic DNA-binding proteins. Posttranslational modifications on N-terminal tails of histones that form nucleosomes are often associated with distinct biological functions. Some theories suggest that one of these modifications, the phosphorylation of histone H3 at serine 10 (H3S10ph) plays a role in both chromosome condensation and sister chromatid cohesion. Although histones and some of their modifications are highly conserved, studies have shown that role and distribution of H3S10ph may differ between species. We evaluated the pattern of H3 phosphorylation using immunodetection during mitosis and meiosis in both diploid and tetraploid genotypes of Brachiaria species. Results revealed differences in chromosome distribution of H3S10ph when mitosis and meiosis were compared. Whole chromosomes were phosphorylated during meiosis I, whereas phosphorylation was restricted to the pericentromeric region in both meiosis II and mitosis. There was no variation in phosphorylation patterns between Brachiaria species and diploid and tetraploid genotypes. Regarding spatiotemporal coordination in the Brachiaria species evaluated, H3S10ph is related to maintenance of sister chromatid cohesion during cell divisions.
