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
We report the distribution of several histone modifications along the arms and in centromeric regions of somatic chromosomes of maize, including the supernumerary B chromosome. Acetylated H3 and H4 as well as H3K4me2, modifications associated with euchromatin, were enriched in the distal parts of the A chromosomes, but were progressively depleted toward the centromeres of the A chromosomes and were depleted in the heterochromatic portions of the B chromosome. Classical histone modifications associated with heterochromatin, including H3K9me2, H3K27me1 and H3K27me2, were distributed throughout both A and B chromosomes. However, H3K27me2 showed a reduced level on the B chromosome compared with the A chromosomes and was not associated with some classes of constitutive heterochromatin. We monitored the presence of each histone modification in the centromeric regions using a YFP-tagged centromere-specific histone, CENH3. We observed the presence of H3K9me2 and absence of H3K4me2 in the centromeric regions of both A and B chromosomes of maize, which is in contrast to the presence of H3K4me2 and absence of H3K9me2 in animal centromeres. These results show a diversity of epigenetic modifications associated with centromeric chromatin in different eukaryotes.
