Effects of pyruvate and dimethyl-α-ketoglutarate, either alone or in combination, on pre- and post-implantation development of mouse zygotes cultured in vitro.
Article in Reproductive medicine and biology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeDimethyl α-ketoglutarate (dm-α-KG) promotes in vitro development to blastocysts of C57BL/6J X C3He F1 mouse zygotes cultured in medium lacking pyruvate. Here, we examined the effects of pyruvate and dm-α-KG on in vitro development to blastocysts of ICR mouse zygotes and their post-implantation developmental ability.
methodsZygotes were cultured in medium with pyruvate at 0-0.2 mmol/L in the presence or absence of 1 mmol/L dm-α-KG for 96 hours and evaluated for blastocyst formation rates. The resultant blastocysts were non-surgically transferred to surrogates and evaluated for birth rates.
resultsIn medium lacking pyruvate, zygotes could not develop beyond the two-cell stage, in the presence or absence of dm-α-KG. However, the blastocyst formation rate in medium with 0.01 mmol/L pyruvate (12%) was markedly increased with addition of dm-α-KG (49%). Around 80% of embryos developed to blastocysts in medium with 0.2 mmol/L pyruvate, in the presence or absence of dm-α-KG. Importantly, birth rate was markedly improved by treatment with 0.2 mmol/L pyruvate and dm-αKG (31.0%), compared with those with pyruvate treatment alone (16.3%).
conclusionsPyruvate and dm-α-KG synergistically work during in vitro culture to markedly improve the blastocyst formation rate and post-implantation developmental ability of the resultant blastocysts in ICR mice.
