Evaluation of biofilm formation, antimicrobial pattern, and typing of Stenotrophomonas maltophilia isolated from clinical sources in Brazil.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
This study aimed to evaluate the biofilm formation and disinfectant tolerance of Stenotrophomonas maltophilia strains originated from hospitalized patients during the COVID-19 pandemic. Nine strains were isolated from different clinical departments at a hospital in Brazil, were identified by VITEK®2, Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry, 16S rRNA sequencing, and 23S rRNA PCR. Enterobacterial Repetitive Intergenic Consensus-Polymerase Chain Reaction (ERIC-PCR), Fourier-transform infrared (FTIR) spectroscopy, antimicrobial susceptibility testing, and biofilm formation and disinfectant tolerance tests were applied. ERIC-PCR, FTIR, and VITEK®2 results exhibited no correlation between the strains, indicating different origins in the Hospital. Most strains expressed resistance to several antibiotics but minocycline and cefiderocol, which were therefore regarded as optimistic therapy options. All strains produced biofilms on polystyrene and most of them (n = 7) on stainless-steel surfaces. The sodium hypochlorite 0.5% was shown to be the most efficient disinfectant for biofilm eradication. Biofilm formation and tolerance to disinfectants analysis indicated the requirement for efficient cleaning protocols to eliminate S. maltophilia contamination.
