In vitro and in vivo activities of the diazabicyclooctane OP0595 against AmpC-derepressed Pseudomonas aeruginosa.
Article in The Journal of antibiotics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
Pseudomonas aeruginosa is a common cause for healthcare-associated infections, which have been historically treated by antipseudomonal β-lactam agents in the clinical setting. However, P. aeruginosa has evolved to overcome these β-lactam agents via multiple endogenous resistance mechanisms, including derepression of the chromosomal cephalosporinase (AmpC). In this article, we investigated the effective concentration of OP0595 for combination with piperacillin, cefepime or meropenem in in vitro susceptibility tests, and the antibacterial activity of cefepime in combination with OP0595 in both in vitro time-kill studies and in vivo murine thigh infection model study with AmpC-derepressed P. aeruginosa. The sufficient combinational concentration of OP0595 was a 4 μg ml
