1 · What the graph read from it

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.

2 · The registry

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 used chromosome painting to show directly that chromosomes occupy fixed positions in the nuclei of mammal but not chicken sperm. We found that the positions of homologous chromosomes are conserved in sperm of two marsupial species that diverged 50-60 million years ago. We also discovered that the X chromosome lies in the region that makes first contact with the egg in marsupial and monotreme mammals, as well as eutherians, and suggest that this position may be related to its propensity for inactivation, and its high rate of loss from ICSI embryos. We propose that nuclear architecture in sperm is important for spatial chromatin differentiation and normal development of the fertilized egg, and evolved along with mammal-specific regulatory systems such as X inactivation and genomic imprinting.
