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

objectiveTo construct a W203X-mutant mouse model of cblC type methylmalonic acidemia based on the CRISPR/Cas9 technology.

methodsAt first, BLAST was used to compare the conservative nature of the cblC gene and protein sequences in humans and mice, and then, the CRISPR/Cas9 technology was used for microinjection of mouse fertilized eggs to obtain heterozygous F1 mice. Hybridization was performed for these mice to obtain homozygous W203X-mutant mice. The blood level of the metabolite propionyl carnitine (C3) was measured for homozygous mutant mice, heterozygous littermates, and wild-type mice.

resultsThe gene and protein sequences of MMACHC, the pathogenic gene for cblC type methylmalonic acidemia, were highly conserved in humans and mice. The homozygous W203X-mutant mice were successfully obtained by the CRISPR/Cas9 technology, and there was a significant increase in C3 in these mice at 24 hours after birth (P<0.001).

conclusionsA W203X-mutant mouse model of cblC type methylmalonic acidemia is successfully constructed by the CRISPR/Cas9 technology.
