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

backgroundSea urchins have contributed to knowledge of fertilization, embryonic development, and cell physiology for 150 years. Their evolutionary position, as basal deuterostomes, and their long background in developmental biology motivate establishing a genetically enabled sea urchin species. Because of its relatively short generation time of 4-6 months and ease of culture, our lab has focused on the California sea urchin Lytechinus pictus as a multigenerational model and produced knockout and transgenic lines using this species. To ensure that diverse genetic lines can be preserved, methods must be developed to cryopreserve gametes and embryos. We have previously reported methods for cryopreservation of sperm, but robust methods to preserve embryos remain lacking.

resultsHere, we describe a relatively simple method to cryopreserve late gastrulae embryos of L. pictus. Importantly, we show that, after thawing and culturing, the embryos progress through larval development, undergo metamorphosis, and yield juvenile adults, indicating the method is robust.

conclusionThe cryopreservation of embryos is an important advance that will facilitate the biobanking, sharing, and long-term preservation of diverse genetic lines. This method may also eventually prove useful for cryopreservation of embryos of other marine invertebrates.
