Rye terminal neocentromeres: characterisation of the underlying DNA and chromatin structure.
Article in Chromosoma, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
We have studied rye plants with neocentromeres on the terminal regions of the chromosomes. These neocentromeres only appear in meiosis, they are active together with the normal centromere and move the chromosomal arms polewards from prometaphase to anaphase at both the first and second meiotic divisions. All chromosomes of the normal set may show neocentric activity, but chromosomal arms with terminal heterochromatic blocks, as assessed by C-banding, are significantly more susceptible than those that do not have them. At least three repetitive sequences underlie the neocentromeres: pSc34, pSc74 and pSc200. These sequences are not detectable in B chromosomes, which never showed neocentric activity. Fluorescence in situ hybridisation with these sequences used as probes revealed elongated chromatin extensions on the neocentromeres that have not been observed using other staining techniques. These extensions were never observed in control plants. They suggest a modified chromatin structure, which might be responsible for the interaction with proteins involved in chromosomal movement on the spindle.
