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
Comamonas kerstersii is an environmental microorganism, and clinical infections caused by this species are rare. In this study, the strain CXZJT123 was isolated from gallbladder puncture fluid and identified using a comprehensive approach including morphological observation, mass spectrometry, biochemical identification, 16S rRNA sequencing, and whole-genome sequencing. The morphological characteristics of CXZJT123 were consistent with the Comamonas. Mass spectrometry initially identified the strain as Comamonas aquatica, while biochemical assays demonstrated key features aligning with the Comamonas genus. Phylogenetic analysis of 16S rRNA sequences placed CXZJT123 in the same clade as C. kerstersii (NR 025530.1). Whole-genome sequencing followed by gene annotation using the Non-Redundant Protein Database (NR) revealed the highest gene homology with C. kerstersii. Further genomic analysis using the Virulence Factors of Pathogenic Bacteria (VFDB) and the Comprehensive Antibiotic Research Database (CARD) identified the presence of virulence genes, including those encoding flagella (flg series) and biofilm formation (pil series), as well as antibiotic resistance genes such as macB, arlR, and evgS. This study presents the first reported isolation of C. kerstersii isolated from gallbladder puncture fluid. The findings contribute valuable insights into the identification, genomic characteristics, and potential pathogenicity of C. kerstersii, providing a useful reference for the diagnosis and management of related infections.
