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

We constructed a phagemid consisting of the whole genome of the Neisseria gonorrhoeae bacteriophage NgoΦ6 cloned into a pBluescript plasmid derivative lacking the f1 origin of replication (named pBS::Φ6). Escherichia coli cells harboring pBS::Φ6 were able to produce a biologically active phagemid, NgoΦ6fm, capable of infecting, integrating its DNA into the chromosome of, and producing progeny phagemids in, a variety of taxonomically distant Gram-negative bacteria, including E. coli, Haemophilus influenzae, Neisseria sicca, Pseudomonas sp., and Paracoccus methylutens. A derivative of pBS::Φ6 lacking the phage orf7 gene, a positional homolog of filamentous phage proteins that mediate the interaction between the phage and the bacterial pilus, was capable of producing phagemid particles that were able to infect E. coli, Haemophilus influenzae, N. sicca, Pseudomonas sp., and Paracoccus methylutens, indicating that NgoΦ6 infects cells of these species using a mechanism that does not involve the Orf7 gene product and that NgoΦ6 initiates infection through a novel process in these species. We further demonstrate that the establishment of the lysogenic state does not require an active phage integrase. Since phagemid particles were capable of infecting diverse hosts, this indicates that NgoΦ6 is the first broad-host-range filamentous bacteriophage described.
