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

More than 180 individual phages infecting hosts in the phylum Actinobacteria have been sequenced and grouped into Cluster A because of their similar overall nucleotide sequences and genome architectures. These Cluster A phages are either temperate or derivatives of temperate parents, and most have an integration cassette near the centre of the genome containing an integrase gene and attP. However, about 20% of the phages lack an integration cassette, which is replaced by a 1.4 kbp segment with predicted partitioning functions, including plasmid-like parA and parB genes. Phage RedRock forms stable lysogens in Mycobacterium smegmatis in which the prophage replicates at 2.4 copies/chromosome and the partitioning system confers prophage maintenance. The parAB genes are expressed upon RedRock infection of M. smegmatis, but are downregulated once lysogeny is established by binding of RedRock ParB to parS-L, one of two centromere-like sites flanking the parAB genes. The RedRock parS-L and parS-R sites are composed of eight directly repeated copies of an 8 bp motif that is recognized by ParB. The actinobacteriophage parABS cassettes span considerable sequence diversity and specificity, providing a suite of tools for use in mycobacterial genetics.
