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

Temperate bacterial viruses (phages) can transition between lysis-replicating and killing the host-and lysogeny, that is, existing as dormant prophages while keeping the host viable. Recent research showed that on invading a naïve cell, some phages communicate using a peptide signal, termed arbitrium, to control the decision of entering lysogeny. Whether communication can also serve to regulate exit from lysogeny (known as phage induction) is unclear. Here we show that arbitrium-coding prophages continue to communicate from the lysogenic state by secreting and sensing the arbitrium signal. Signalling represses DNA damage-dependent phage induction, enabling prophages to reduce the induction rate when surrounded by other lysogens. We show that in certain phages, DNA damage and communication converge to regulate the expression of the arbitrium-responsive gene aimX, while in others integration of DNA damage and communication occurs downstream of aimX expression. Additionally, signalling by prophages tilts the decision of nearby infecting phages towards lysogeny. Altogether, we find that phages use small-molecule communication throughout their entire life cycle to sense the abundance of lysogens in the population, thus avoiding lysis when they are likely to encounter established lysogens rather than permissive uninfected hosts.
