Ceftazidime-avibactam, meropenen-vaborbactam, and imipenem-relebactam in combination with aztreonam against multidrug-resistant, metallo-β-lactamase-producing Klebsiella pneumoniae.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 papers, 3 of them syntheses that pooled 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.
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 spread of multidrug-resistant (MDR), metallo-β-lactamase (MBL)-producing Klebsiella pneumoniae represents a major therapeutic challenge. The newly introduced β-lactam-β-lactamase inhibitors (BLBLIs), ceftazidime/avibactam (CAZ/AVI), meropenem/vaborbactam (M/V), and imipenem/relebactam (I/R) are inactive against MBLs. The aim of this study was to evaluate the in vitro efficacy of aztreonam (ATM) in combination with CAZ/AVI, M/V, and I/R against 40 MDR, MBL-producing, and serine-β-lactamases co-producing Klebsiella pneumoniae using the Etest method. Synergy was defined as a fractional inhibitory concentration index ≤0.5. All isolates were resistant to ATM, CAZ/AVI, and I/R and 38/40 (95%) were resistant to M/V. Synergy was observed in 97.5% in the combinations CAZ/AVI-ATM, and I/R-ATM and in 72.5% in the combination M/V-ATM. Further clinical studies are required to confirm the efficacy of these antimicrobial combinations.
