Klebsiella pneumoniae from community-acquired infections and an urban river share antimicrobial resistance profiles and high-risk lineages but differ in virulence.

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
Klebsiella pneumoniae poses a significant public health threat, but the relationship between community-acquired (CA) infections and environmental isolates remains poorly understood. Therefore, this study aimed to assess whether K. pneumoniae from CA infections share microbiological and molecular features with isolates recovered from an urban river in Salvador, Brazil. A total of 115 isolates, including 65 from CA infections and 50 from river water, were analyzed using antimicrobial susceptibility testing, β-lactamase and virulence gene detection, and multilocus sequence typing (MLST). Resistance rates were similar between groups, including multidrug resistance (24.6% vs. 22.0%; p > 0.05) and carbapenem resistance (4.6% vs. 4.0%; p > 0.05). β-lactamase gene detection was consistent with observed resistance patterns, with bla
