Methylated-rich regions and tandem repeat arrays along the chromosome complement of Colpodium versicolor (Stev.) Schmalh.
Article in Protoplasma, 2009. 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
The grass Colpodium versicolor (Stev.) Schmalh is one of six angiosperms with extremely reduced chromosome set 2n = 2x = 4. The chromosome complement of this species was studied. The DNA methylation pattern was determined with a specific monoclonal antiboby. 5-Methylcytosine residues are present in different chromosomal sites, with specific occurrence, some methylated bands showing differences between homologous chromosomes. Moreover, a fluorescent in situ hybridisation with telomere repeats and 45S rDNA sequences were performed. Hybridisation signals of telomeric repeats are detectable at the distal ends of the two pair of chromosomes, while 45S rDNA is localised in one chromosomal site, corresponding to the secondary constriction. In addition, 45S rDNA, as well as telomere-associated sequences, results to be 5-methylcytosine-enriched. The results are discussed and compared with those previously obtained in other plant systems 2n = 4 with the aim to enable a better knowledge of the lengthwise differentiation of this chromosome complement.
