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
backgroundThe emergence of ESBL/AmpC-producing K. pneumoniae is a significant concern in humans and veterinary medicine. This study aims to ascertain the antimicrobial resistance profiles and molecular characteristics of ESBL/AmpC-producing K. pneumoniae isolated from diseased companion animals during 2018-2023 in South Korea.
methodsThe obtained isolates (dogs, n = 130 and cats, n = 30) from urine, genital organs, diarrheal feces, skin/ear, and respiratory tract were assessed for antimicrobial susceptibility by broth microdilution. Molecular characteristics were determined by polymerase chain reaction (PCR), multi-locus sequence typing (MLST), and pulsed-field gel electrophoresis (PFGE).
resultsAmong the tested antimicrobials, the highest resistance rates were demonstrated for tetracycline, followed by cefazolin. In the sample levels, isolates from non-digestive tract showed overall higher antimicrobial resistance rates than digestive tract samples for both dogs and cats. In general, 25% (40/160) of the K. pneumoniae isolates harbored ESBL and/or AmpC genes. Of them, ESBL was identified in 30 isolates, with bla
conclusionTaken together, the findings emphasize the role of dogs and cats as reservoirs of antimicrobial-resistant K. pneumoniae that could be transmitted to humans. Therefore, it is necessary to conduct continuous surveillance and ensure the judicious use of antimicrobials in companion animals.
