Selection of Vaccinia Virus Recombinants Using CRISPR/Cas9.
Article in Bio-protocol, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The engineering of poxvirus genomes is fundamental to primary and applied virology research. Indeed, recombinant poxviruses form the basis for many novel vaccines and virotherapies but producing and purifying these viruses can be arduous. In recent years, CRISPR/Cas9 has become the favoured approach for genome manipulation due to its speed and high success rate. However, recent data suggests poxvirus genomes are not repaired well following Cas9 cleavage. As a result, CRISPR/Cas9 is inefficient as an editing tool, but very effective as a programmable selection agent. Here, we describe protocols for the generation and enrichment of recombinant vaccinia viruses using targeted Cas9 as a selection tool. This novel use of Cas9 is a simple addition to current homologous recombination-based methods that are widespread in the field, facilitating implementation in laboratories already working with poxviruses. This is also the first method that allows for isolation of new vaccinia viruses in less than a fortnight, without the need to incorporate a marker gene or manipulation of large poxvirus genomes
