Identification phenotypic and genotypic characterization of biofilm formation in Escherichia coli isolated from urinary tract infections and their antibiotics resistance.
Article in BMC research notes, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
objectiveUrinary tract infections (UTIs) are the most common infectious diseases, and Escherichia coli is the most common pathogen isolated from patients with UTIs. The products of sfa, afa and foc genes are important for binding of the bacterium to urinary tract epithelium. Our aim was to investigate these genes in E. colis isolated from patients with UTIS. The frequencies of the genes were determined using PCR. Biofilm formation and antibiotic resistance rates were determined using microtiter plate and disk diffusion methods, respectively. The P < 0.05 was considered statistically significant.
resultsThe frequencies of sfa, afa and foc were 75.3%, 17.5% and 22.5%, respectively showing a significantly higher prevalence of the sfa gene. The most effective antibiotics against the E. colis were nitrofurantoin and amikacin. The highest microbial resistance rates were also observed against amoxicillin and ampicillin. Furthermore, 12.7%, 6.3%, 74.7% and 6.3% of the isolates showed strong, moderate, weak capacities and no connections to form biofilms, respectively. The expression of the sfa gene was significantly associated with forming strong biofilms. Regarding the variabilities in the characteristics of E. coli strains associated with UTIs, it seems reasonable to adjust diagnostic and therapeutic methods according to the regional microbial characteristics.
