Biochemical Insights into Imipenem Collateral Susceptibility Driven by
Article in Antimicrobial agents and chemotherapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Several Pseudomonas aeruginosa AmpC mutants have emerged that exhibit enhanced activity against ceftazidime and ceftolozane, while also evading inhibition by avibactam. Interestingly, P. aeruginosa strains harboring these AmpC mutations fortuitously exhibit enhanced carbapenem susceptibility. This acquired susceptibility was investigated by comparing the degradation of imipenem by wild-type and cephalosporin-resistant AmpC. We show that cephalosporin-resistant AmpC enzymes lose their efficacy for hydrolyzing imipenem and suggest that this may be due to their increased flexibility and dynamics relative to the wild type.
