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

Previous characterization of Lytµ1/6, an endolysin from Streptomyces aureofaciens phage µ1/6, suggested that the N-terminal domain is responsible for the catalytic activity of Lytµ1/6. Mutational analyses (deletions and site-directed mutagenesis) demonstrated that lytic activity of Lytµ1/6 relies on the N-terminal part of about 200 amino acid residues. Various C-terminally truncated versions of Lytµ1/6 failed to cause lysis, indicating the necessity of the CBD for full enzyme activity. Functional analysis of the point mutants suggested that the residues K27, H31, E109, H176, and D184 were essential for lytic activity of the µ1/6 endolysin. Further characterization of the purified Lytµ1/6 revealed that this endolysin is an N-acetylmuramoyl-L-alanine amidase which seems to be unrelated to any of the known conserved catalytic domains of phage endolysins or bacterial autolysins.
