The role of prokaryotic argonautes in resistance to type II topoisomerases poison ciprofloxacin.
Review in Biochemical Society transactions, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Argonaute proteins are programmable nucleases found in all domains of life. Eukaryotic argonautes (eAgos) participate in genetic regulation, antiviral response, and transposon silencing during RNA interference. Prokaryotic argonautes (pAgos) are much more diverse than eAgos and have been implicated in defense against invading genetic elements. Recently, it was shown that pAgos protect bacterial cells from a topoisomerase poison ciprofloxacin, raising a possibility that they may play a role in DNA replication and/or repair. Here, we discuss possible models of pAgo-mediated ciprofloxacin resistance. We propose that pAgos could (i) participate in chromosome decatenation as a backup to topoisomerases; (ii) participate in the processing of DNA repair intermediates formed after topoisomerase poisoning, or (iii) induce SOS response that generally affects DNA repair and antibiotic resistance. These hypotheses should guide future investigations of the involvement of pAgos in the emergence of resistance to ciprofloxacin and, possibly, other antibiotics.
