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

Bacterial CBASS immune defense systems commonly kill virally infected cells by degrading genomic DNA in a form of cell suicide or abortive infection. We present a high-resolution structure of the CBASS effector Cap5, activated by a cyclic nucleotide, in the act of digesting DNA via tetrameric HNH endonuclease domains. Two HNH domains are in a catalytically active state for cleavage of the DNA strands, whereas the other two HNH domains are in a topologically distinct catalytically inactive state for simply DNA binding. The four HNH domains track one face of the DNA and mark an enzyme that acts as a stand-alone non-specific nuclease. We also show that chromosomally encoded CBASS Cap5 can be extrinsically activated by a cyclic nucleotide, as a step towards potential antibiotics.
