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

Temperate phages are potential therapeutic agents, but only a few temperate phages infecting multidrug-resistant Acinetobacter baumannii have been identified. In this study, we isolated 5W, a temperate phage that infects multidrug-resistant A. baumannii, from pond water using the enrichment method. A member of the Siphoviridae family, 5W has a narrow host range and infected only four of 19 A. baumannii clinical isolates. It exhibited rapid adsorption (> 90% in 6 min), a latency period of 20 min, and a burst size of ~ 180 plaque-forming units (PFU/cell). 5W contains a linear double-stranded DNA (dsDNA) genome of 43,032 bp with a GC content of 39.85%. The 5W genome contains 61 open reading frames, including lysogen-forming genes, but lacks any known virulence and antibiotic resistance genes. The lysin of 5W is an N-acetyl-β-D-muramidase belonging to the GH_108 family. The α-helical structure and highly positively charged amino acids in the C-terminal region indicate potential antibacterial activity against A. baumannii, and the M/S subunits of the restriction endonuclease are inserted into the lysogenic gene cluster. Comparative genome analysis revealed high similarity with two different prophages in A. baumannii ABCR01, suggesting that 5W may be derived from recombination of other prophages.
