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

Gynogenesis is a form of parthenogenesis in which sperm is required to activate the egg but contributes no genetic material to the embryo. In Xenopus, gynogenetic embryos can be created by using UV-irradiated sperm in in vitro fertilization and then preventing the formation of the second polar body, so the embryo retains two maternal chromosomes. The method is very simple, relies on standard laboratory equipment, and can be used to create homozygous embryos from heterozygous female carriers without the need to raise an F1 generation for in-crosses.
