Media optimization to promote rat embryonic development to the blastocyst stage in vitro.
Article in Theriogenology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Efficient model production in rats that incorporates newly developed genetic editing and embryo transfer tools, such as CRISPR/Cas9 technology and non-surgical embryo transfer, requires availability of an optimal embryo culture system. However, current technologies for in vitro manipulation of rat gametes, including embryo culture techniques, are less advanced compared to those in mice. In this study, we (1) identified a culture medium that was able to support optimal rat embryonic development by comparing two rat culture media: mR1ECM (modified rat 1-cell embryo culture medium) and KSOM-R (modified potassium simplex optimized medium for rats), and (2) evaluated the effect of glutamine dipeptides: alanyl-l-glutamine and glycyl-l-glutamine, on rat embryonic development. We also investigated the possibility of simplifying the KSOM-R culture procedure by increasing the volume of culture medium, reducing the need for daily medium changes. The results showed that rat embryos cultured in KSOM-R developed faster than those cultured in mR1ECM. Both alanyl-l-glutamine and glycyl-l-glutamine showed detrimental effects on rat embryonic development when supplemented in KSOM-R at the same concentration as glutamine. By increasing the volume of KSOM-R, rat zygotes were able to develop without daily medium refreshment at a similar rate and developmental competence as those in smaller volumes with daily medium changes. These results represent important improvements to rat embryo culture methods and will assist in more efficient production of rat models.
