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

Virulent phages, characterized by an obligatory lytic cycle resulting in the death of their bacterial hosts, are assumed to lack the ability to persist within bacterial colonies. Consequently, when bacterial isolates are sequenced, the resulting assemblies are not expected to contain virulent phage genomes. Here we test this assumption at scale by analysing over 267,000 publicly available Escherichia assemblies. Surprisingly, we identified 373 virulent phage genomes within these assemblies. Such viral genomes are associated with specific phage taxa and especially with very large (jumbo) phages such as the phage nucleus-forming family Chimalliviridae. Multiple lines of evidence from culture experiments and bioinformatic analyses suggest that these virulent phage genomes arise from persistent infections without substantial host mortality. We also identified 285 related phage genomes in bacterial taxa beyond Escherichia, highlighting the frequency of as-yet-uncharacterized persistent phages. Our findings challenge the traditional virulent-temperate dichotomy and point to the prevalence of non-canonical phage lifestyles.
