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

In early years, Dr. Donald S. Coffey fostered the development of a new model for the organization of DNA in the sperm nucleus that had many unexpected similarities to that of somatic cells. This was surprising because it was well known that mammalian sperm DNA is more compact than the DNA in mitotic chromosomes, and the fact that some of the major structural components of somatic cell DNA organization were retained in the sperm cell was not predicted. The highly compact sperm DNA is organized into loop domains that are attached at their bases to a proteinaceous nuclear matrix, at specific matrix attachment regions (MARs). This organization is required for DNA synthesis of the paternal genome hours after fertilization, and also participates in an apoptotic-like degradation of the DNA under certain conditions. The tight packaging of the sperm chromatin is due entirely to the replacement of histones by protamines, but the sperm DNA loop domain organization is not changed by this transition, and is probably inherited by the paternal pronucleus in the newly formed embryo.
