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
Chromosome arrangements have been studied in metaphase and interphase somatic cells and in sperm of many animal species, but there are conflicting data and it is still not clear whether chromosomes are arranged randomly or non-randomly. We used chromosome painting to reveal the positions of chromosomes in marsupial sperm. Marsupials are ideally suited for these studies because they have only a few large chromosomes. Here, we show that chromosomes occupy fixed positions in the immature and mature sperm of Sminthopsis crassicaudata. We suggest that the non-random arrangement of chromosomes in marsupial sperm may be important in establishing chromosome arrangement and patterns of gene activity within the developing embryo.
