Clinical presentation and outcomes in non-maltophilia Stenotrophomonas spp. bloodstream infections.
Article in Scientific reports, 2026. 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
Stenotrophomonas maltophilia complex is an important nosocomial cause of bacteraemia. The complex comprises multiple species, but their relative clinical and genomic significance remains unclear. We examined clinical and genomic differences between S. maltophilia and non-S. maltophilia species to better understand their virulence and implications for patient care. Hospitalized adult patients (≥ 21 years) between January 2022 and June 2024 with Stenotrophomonas species bacteraemia were examined. Clinical data were extracted from electronic medical records. Whole-genome sequencing was performed on all isolates, with species assignment confirmed by average nucleotide identity. S. maltophilia and non-S. maltophilia species were compared. Fifty-three S. maltophilia complex isolates were identified, of which 45 had clinical data. S. maltophilia predominated (n = 32), followed by S. pavanii (n = 7), S. sepilia (n = 4), S. muris (n = 1), and S. geniculata (n = 1). S. maltophilia isolates formed multiple clades with diverse sequence types, consistent with both clonal expansion and ongoing diversification. Virulence genes, including stmPr, smoR, and iron acquisition-associated genes were conserved across S. maltophilia lineages, but stmPr1 was less frequently observed in non-S. maltophilia. Most infections were line-related. Pneumonia-associated bacteraemia appeared more frequently among with S. maltophilia infections. Polymicrobial bacteraemia appeared more commonly in non-S. maltophilia infections. Mortality was similar between groups, but recurrence of infection within one year occurred only in S. maltophilia. Compared with non-S. maltophilia, S. maltophilia appeared to be associated with pneumonia and recurrent bacteraemia episodes, although mortality was similar. These exploratory findings suggest potential differences within the complex, but require validation in larger studies.
