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
Aztreonam-avibactam (AZA) is a new monobactam/beta-lactamase inhibitor combination that recently received regulatory approval in the United States (U.S.) and Europe. In this study, we evaluated the performance of ETEST AZA, a gradient diffusion method, compared to reference broth microdilution for 650 challenge ( IMPORTANCE: Aztreonam-avibactam (AZA) is a novel monobactam/β-lactamase inhibitor combination approved for clinical use in the United States and Europe in 2025 and 2024, respectively. It is indicated for the treatment of multidrug-resistant Gram-negative bacteria that produce multiple classes of β-lactamases. Until recently, antimicrobial susceptibility testing for this combined agent relied on broth disk elution or microdilution using ceftazidime-avibactam and aztreonam combined. In this study, we evaluated the performance of the bioMérieux ETEST AZA gradient diffusion strip as a more streamlined method for clinical microbiology laboratories. Testing of 650
