ArticleAntimicrobial agents and chemotherapy2022
Article in Antimicrobial agents and chemotherapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 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
Ceftolozane-tazobactam (C/T), imipenem-relebactam (IMR), and ceftazidime-avibactam (CZA) were tested against 2,531 P. aeruginosa strains isolated from patients in the United States from 2018 to 2020 as part of the SMART (Study for Monitoring Antimicrobial Resistance Trends) surveillance program. MICs were determined by CLSI broth microdilution and interpreted using CLSI M100 (2021) breakpoints. Imipenem-, IMR-, or C/T-nonsusceptible isolates were screened for β-lactamase genes: 96.4% of all isolates and ≥70% of multidrug-resistant (MDR), pan-β-lactam-nonsusceptible, and difficult-to-treat resistance (DTR) isolates were C/T-susceptible; 52.2% of C/T-nonsusceptible isolates remained susceptible to IMR compared to 38.9% for CZA; and 1.7% of isolates tested were nonsusceptible to both C/T and IMR versus 2.2% of isolates with a C/T-nonsusceptible and CZA-resistant phenotype (a difference of 12 isolates). C/T and IMR modal MICs for pan-β-lactam-nonsusceptible isolates remained at or below their respective susceptible MIC breakpoints from 2018 to 2020, while the modal MIC for CZA increased 2-fold from 2018 to 2019 and exceeded the CZA-susceptible MIC breakpoint in both 2019 and 2020. Only six of 802 molecularly characterized isolates carried a metallo-β-lactamase, and two isolates carried a GES carbapenemase. Most P. aeruginosa isolates were C/T-susceptible, including many with MDR, pan-β-lactam-nonsusceptible, DTR, CZA-resistant, and IMR-nonsusceptible phenotypes. While C/T was the most active antipseudomonal agent, IMR demonstrated greater activity than CZA against isolates nonsusceptible to C/T.
