Oligo-Mediated Recombineering and its Use for Making SNPs, Knockouts, Insertions, and Fusions in Mycobacterium tuberculosis.
Article in Methods in molecular biology (Clifton, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Phage recombination systems have been instrumental in the development of gene modification technologies for bacterial pathogens. In particular, the Che9 phage RecET system has been used successfully for over 10 years for making gene knockouts and fusions in Mycobacterium tuberculosis. This "recombineering" technology typically uses linear dsDNA substrates that contain a drug-resistance marker flanked by (up to) 500 base pairs of DNA homologous to the target site. Less often employed in mycobacterial recombineering is the use of oligonucleotides, which require only the action of the RecT annealase to align oligos to ssDNA regions of the replication fork, for subsequent incorporation into the chromosome. Despite the higher frequency of such events relative to dsDNA-promoted recombineering, oligo-mediated changes generally suffer from the disadvantage of not being selectable, thus making them harder to isolate. This chapter discusses steps and methodologies that increase the frequencies of finding oligo-mediated events, including the transfer of single nucleotide polymorphisms (SNPs) to mycobacterial chromosomes, and the use of oligos in conjunction with the mycobacterial phage Bxb1 site-specific recombination system for the easy generation of knockouts, insertion, and fusions, in a protocol known as ORBIT.
