Highly efficient RNAi and Cas9-based auto-cloning systems for C. elegans research.
Article in Nucleic acids research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 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
RNA interference (RNAi) technology used for the functional analysis of Caenorhabditis elegans genes frequently leads to phenotypes with low penetrance or even proves completely ineffective. The methods previously developed to solve this problem were built on mutant genetic backgrounds, such as those defective for rrf-3, in which endogenous RNAi pathways are overexpressed. These mutations, however, interferes with many other genetic pathways so that the detected phenotype cannot always be clearly linked to the RNAi-exposed gene. In addition, using RNAi-overexpressing mutant backgrounds requires time-consuming genetic crossing. Here, we present an improved RNAi vector that produces specific double-stranded RNA species only, and thereby significantly stronger phenotypes than the standard gene knockdown vector. The further advantage of the new RNAi vector is that the detected phenotype can be specifically linked to the gene silenced. We also created a new all-in-one C. elegans Cas9 vector whose spacer sequence is much easier to replace. Both new vectors include a novel CRISPR/Cas9-based auto-cloning vector system rendering needless the use of restriction and ligase enzymes in generating DNA constructs. This novel, efficient RNAi and auto-cloning Cas9 systems can be easily adapted to any other genetic model.
