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

Host-mediated natural competence for transformation of DNA and mobile genetic element (MGE)-driven conjugation and transduction are key modes of horizontal gene transfer. While these mechanisms are traditionally believed to shape bacterial evolution by enabling the acquisition of new genetic traits, numerous studies have elucidated an antagonistic relationship between natural transformation and MGEs. A new role of natural transformation as a chromosome-curing mechanism has now been proposed. Experimental data, along with mathematical models, suggest that transformation can eliminate deleterious MGEs. Supporting this hypothesis, MGEs have been shown to use various mechanisms to decrease or block transformability, such as disrupting competence genes, regulating the development of competence, hindering DNA uptake machinery, producing DNases that target the exogenous (transforming) DNA, and causing lysis of competent cells. A few examples of synergistic relationships between natural transformation and MGEs have also been reported, with natural transformation facilitating MGE transfer and phages enhancing transformation by supplying extracellular DNA through lysis and promoting competence via kin discrimination. Given the complexity of the relationships between natural transformation and MGEs, the balance between antagonism and synergy likely depends on specific selection pressures in a given context. The evidence collected here indicates a continuous conflict over horizontal gene transfer in bacteria, with semiautonomous MGEs attempting to disrupt host-controlled DNA acquisition, while host competence mechanisms work to resist MGE interference.
