In vitro activity of aztreonam-avibactam against a global collection of Gram-negative pathogens from 2012 and 2013.

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
The combination of aztreonam plus avibactam is being developed for use in infections caused by metallo-β-lactamase-producing Enterobacteriaceae strains that also produce serine β-lactamases. The in vitro activities of aztreonam-avibactam and comparator antimicrobials were determined against year 2012 and 2013 clinical isolates of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii using the broth microdilution methodology recommended by the Clinical and Laboratory Standards Institute (CLSI). A total of 28,501 unique clinical isolates were obtained from patients in 190 medical centers within 39 countries. MIC90 values of aztreonam and aztreonam-avibactam against all collected isolates of Enterobacteriaceae (n = 23,516) were 64 and 0.12 μg/ml, respectively, with 76.2% of the isolates inhibited by ≤4 μg/ml of aztreonam (the CLSI breakpoint) and 99.9% of the isolates inhibited by ≤4 μg/ml of aztreonam-avibactam using a fixed concentration of 4 μg/ml of avibactam. The MIC90 was 32 μg/ml for both aztreonam and aztreonam-avibactam against P. aeruginosa (n = 3,766). Aztreonam alone or in combination with avibactam had no in vitro activity against isolates of A. baumannii. PCR and sequencing were used to characterize 5,076 isolates for β-lactamase genes. Aztreonam was not active against most Enterobacteriaceae isolates producing class A or class C enzymes alone or in combination with class B metallo-β-lactamases. In contrast, >99% of Enterobacteriaceae isolates producing all observed Ambler classes of β-lactamase enzymes were inhibited by ≤4 μg/ml aztreonam in combination with avibactam, including isolates that produced IMP-, VIM-, and NDM-type metallo-β-lactamases in combination with multiple serine β-lactamases.
