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

Balancer chromosomes are critical tools for genetic research. In C. elegans, reciprocal translocations that lead to aneuploidy have been widely used to maintain lethal and sterile mutations in stable stocks. Here, we generated a set of aneuploidy-free and structurally defined crossover suppressors that contain two overlapping inversions using the CRISPR/Cas9 system. The toolkit includes 13 crossover suppressors and covers approximately 63% of all C. elegans coding genes. Together with the classical intrachromosomal crossover suppressors, the system now covers 89% of the coding genes. We also labeled the created balancers with fluorescent and phenotypic markers. We show that the crossover suppressors are better for embryonic analysis compared with translocational balancers. Additionally, we demonstrate an efficient method to generate lethal alleles by targeting essential genes on a chromosome balanced with a crossover suppressor. The toolkit will allow more efficient experiments in which lethal and sterile mutants can be analyzed.
