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

Nucleic acid modifying enzymes drive diverse defense and counter-defense measures in the evolutionary arms race between viruses and their cellular hosts. Abundant and widespread bacterial viruses (bacteriophage or phage) encode for biosynthetic pathways that install elaborate DNA hypermodifications which protect their genomic DNA from host endonucleases. Here, we establish the molecular basis for the multistep biosynthesis of 6-aminocarboxymethyl-2'-deoxyadenosine (6-NcmdA), a nucleobase hypermodification found in the virion DNA of bacteriophage Mu that leads to restriction evasion in the context of phage-host conflicts. In the first step, we show that Mu-encoded Mom enzyme catalyzes the formation of 6-NcmdA by transferring glycine from charged tRNA
