Prevalence of ESBL producing uropathogens and associated risk factors in catheter associated urinary tract infections a cross-sectional study from Syria.
Article in BMC microbiology, 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
backgroundCatheter-associated urinary tract infections (CAUTIs) are major healthcare-associated infections driven by indwelling devices that facilitate microbial adhesion. This study investigated the distribution of uropathogens in paired urine and catheter samples and evaluated the associations between extended-spectrum beta-lactamase (ESBL) production and clinical factors.
methodsA total of 100 paired urine and catheter samples (n = 100 per sample type) were analyzed using a convenience sampling approach. Clinical criteria for CAUTI diagnosis followed standardized protocols. Statistical significance was set at p < 0.05; however, a formal power calculation was not performed.
resultsCatheter-derived specimens demonstrated a higher bacterial yield compared to urine samples Klebsiella spp and Escherichia coli were the predominant isolates. Opportunistic pathogens like Pseudomonas spp were primarily recovered from catheter surfaces. ESBL production was higher among catheter isolates (42/88 isolates; 47.72%) compared to urine isolates (13/51 isolates; 25.4%). A significant association was observed between catheter-derived isolates and ESBL positivity (OR = 2.66, 95% CI: 1.25-5.67, p < 0.05). Advanced age, prolonged catheterization, and chronic diseases were associated with increased bacterial growth; however, these correlations are unadjusted and may be influenced by confounding factors.
conclusionUrinary catheters serve as reservoirs for MDR uropathogens. While associations were found between device duration and resistance, the use of convenience sampling limits the generalizability of these findings.
