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

RNA-guided endonucleases, once thought to be exclusive to prokaryotes, have been recently identified in eukaryotes and are called Fanzors. They are classified into two clades, Fanzor1 and Fanzor2. Here we present the cryo-electron microscopy structure of Acanthamoeba polyphaga mimivirus Fanzor2, revealing its ωRNA architecture, active site and features involved in transposon-adjacent motif recognition. A comparison to Fanzor1 and TnpB structures highlights divergent evolutionary paths, advancing our understanding of RNA-guided endonucleases.
