Kerstersia gyiorum infection in a patient with chronic suppurative otitis media identified by whole genome sequencing: a case report.
Article in Revista do Instituto de Medicina Tropical de Sao Paulo, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A 52-year-old female patient suffering from chronic suppurative otitis media had a bacterial strain isolated from her ear swab specimens, which could not be identified using conventional methods, but it was eventually identified as Kerstersia gyiorum via whole genome sequencing (WGS). Antimicrobial drug susceptibility testing was conducted on the isolated strain and the results demonstrated its susceptibility to a range of antimicrobial drugs, including ofloxacin, ceftriaxone, and other agents. However, resistance to chloramphenicol was observed. The patient was treated with ofloxacin, ceftriaxone, and dexamethasone, resulting in an improvement in symptoms. This report describes the first documented case of Kerstersia gyiorum causing chronic suppurative otitis media in China. WGS provided definitive species identification in which conventional methods failed, demonstrating its critical role in diagnosing atypical pathogens.
