Multiple maize minichromosomes in meiosis.

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
In this study, four distinct minichromosomes derived from the maize B chromosome, were increased in copy number using the B chromosome's accumulation mechanism, namely nondisjunction at the second pollen mitosis and preferential fertilization of the egg. These minichromosomes provide the unique opportunity to examine the behavior of many copies of a single chromosome in an otherwise diploid background. While multiple copies were associated in multivalent configurations, they often dissociated into univalents or bivalents prior to metaphase I. The largest mini's behavior closely resembled the progenitor B chromosome, but all smaller chromosomes showed failure of sister chromatid cohesion. In addition to the meiotic behavior, we observed many anomalies of univalent behavior and possible heterochromatic fusions of B repeat associated heterochromatin.
