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

Bacteriophages have evolved diverse strategies to overcome host defence mechanisms and to redirect host metabolism to ensure successful propagation. Here we identify a phage protein named Dap1 from Pseudomonas aeruginosa phage PaoP5 that both modulates bacterial host behaviour and contributes to phage fitness. We show that expression of Dap1 in P. aeruginosa reduces bacterial motility and promotes biofilm formation through interference with DipA, a c-di-GMP phosphodiesterase, which causes an increase in c-di-GMP levels that trigger phenotypic changes. Results also show that deletion of dap1 in PaoP5 significantly reduces genome packaging. In this case, Dap1 directly binds to phage HNH endonuclease, prohibiting host Lon-mediated HNH degradation and promoting phage genome packaging. Moreover, PaoP5Δdap1 fails to rescue P. aeruginosa-infected mice, implying the significance of dap1 in phage therapy. Overall, these results highlight remarkable dual functionality in a phage protein, enabling the modulation of host behaviours and ensuring phage fitness.
