"Micronucleoli" in the Xenopus germinal vesicle.
Article in Chromosoma, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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 germinal vesicle of the Xenopus oocyte contains 1500 or more extrachromosomal nucleoli that are assembled on amplified copies of the rRNA genes. Many of these nucleoli have diameters of 10-15 micron, but some are much smaller, ranging down to 1 micron or less. Morphologically the smaller nucleoli or "micronucleoli" resemble the similarly sized B snurposomes, but they can be recognized with appropriate antibody probes (e.g., anti-nucleolin and anti-fibrillarin). We describe here a sensitive fluorescent staining technique that uses avidin and propidium iodide to visualize the rDNA in the amplified nucleoli. Many large nucleoli stain about as brightly as haploid yeast nuclei on the same slides. They presumably contain about 12 Mb of DNA, equivalent to 900 rDNA repeats. The smallest micronucleoli display only a tiny dot of stain, which must correspond to relatively few rDNA repeats.
