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

Bacteria possess numerous defense systems against phage infections, which limit phage infectivity and pose challenges for phage therapy. This study aimed to engineer phages capable of evading these defense systems, using the Tmn defense system as a model. We identified an anti-Tmn protein in the ΦSMS22 phage from the Dhillonvirus genus that inhibits Tmn function in Escherichia coli. Introducing this gene into the Tmn-sensitive ΦKSS9 phage enabled it to evade Tmn immunity. Additionally, we found that a single mutation in the nmad5 gene, a DNA modification enzyme in Dhillonvirus, prevented Tmn from sensing phage infection. By mutating the nmad5 gene in the Tmn-sensitive Dhillonvirus, we demonstrated that engineering phages to evade bacterial sensing mechanisms is another viable strategy. These two phage engineering approaches-introducing anti-defense genes and mutating sensing-related genes-present a promising strategy for establishing effective phage therapy by neutralizing bacterial defense systems.
