Establishment and movement of egg regions revealed by the size class of yolk platelets in Xenopus laevis.

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
Sizes of yolk platelets were measured in sections of oocytes and embryos in Xenopus. It was found that the average size of the largest group of platelets in cells differed between germ layers of neurulae. It was small (3 to 5 μm) in the ectoderm, medium-sized (5 to 8 µm) in the mesoderm, and large (over 8 μm) in the endoderm. Platelets of these size classes formed layers in egg, the yolk gradient, by the end of oocyte maturation. The yolk gradient contained products of the mitochondrial cloud and a part of the germinal vesicle material at certain positions. The layers of small, medium and large platelets in the egg changed their locations to distribute to the ectoderm, mesoderm and endoderm of neurulae, respectively. The yolk layers in the egg thus represented different prospective fates, and a figure describing the locations of these layers could be regarded as a fate map for the one-cell stage. Most of the marginal blastomeres of embryos at cleavage stages consisted of a few parts with different prospective fates. Results were discussed with reference to available fate maps for cleavage stage embryos.
