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

We recently demonstrated that the large Pseudomonas chlororaphis bacteriophage 201φ2-1 assembles a nucleus-like structure that encloses phage DNA and segregates proteins according to function, with DNA processing proteins inside and metabolic enzymes and ribosomes outside the nucleus. Here, we investigate the replication pathway of the Pseudomonas aeruginosa bacteriophages φKZ and φPA3. Bacteriophages φKZ and φPA3 encode a proteinaceous shell that assembles a nucleus-like structure that compartmentalizes proteins and DNA during viral infection. We show that the tubulin-like protein PhuZ encoded by each phage assembles a bipolar spindle that displays dynamic instability and positions the nucleus at midcell. Our results suggest that the phage spindle and nucleus play the same functional role in all three phages, 201φ2-1, φKZ, and φPA3, demonstrating that these key structures are conserved among large Pseudomonas phages.
