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

The chromodomain helicase DNA binding domain 2 (CHD2) gene is an ATPase and a member of the SNF2-like family of helicase-related enzymes. CHD2 plays critical roles in human brain development and function, and homozygous mutation of Chd2 in mice results in perinatal lethality. To further elucidate the effects of chd2, we used CRISPR/Cas9 to create two chd2-knockout strains (fdu901, 11,979-11982delGGGT, and fdu902, 27350delG) in zebrafish. We found that the deformity and mortality rates of fdu901 and fdu902 were higher than those of the wild type. Developmental delay was more obvious and embryo mortality was higher in fdu901 than in fdu902. However, the embryo deformity rate in fdu902 was higher than that in fdu901. Although there were no significant differences in behavior between the two knockout zebrafish and wild-type zebrafish at 7 days post fertilization (dpf), fdu901 and fdu902 zebrafish showed different alterations. The excitability of fdu902 was higher than that of fdu901. Overall, our data demonstrate that two homozygous chd2 knockout mutations were survivable and could be stably inherited and that fdu901 and fdu902 zebrafish differed in behavior and morphology. These two models might be good tools for understanding the functions of the different domains of chd2.
