Urinary tract infections among medical sciences students in Dhamar City, Yemen: prevalence, risk factors, and antimicrobial susceptibility patterns.
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
backgroundUrinary Tract Infections (UTIs) are the most common bacterial infection in humans and a major cause of morbidity and mortality. UTIs affect individuals across all age groups and both genders, with associated complications contributing substantially to the global disease burden. This study aimed to estimate the prevalence and risk factors of urinary tract infections and antimicrobial susceptibility among Al-Hikma University medical sciences students in Dhamar City, Yemen.
methodsA cross sectional descriptive study was conducted from December 2021 to August 2022, included 336 students (211 males; 125 females). The median age of participants was 21 years (range: 17–38 years). Mid-stream urine (MSU) specimens were aseptically collected for UTI microscopic examination and, culture to identify the etiological agents followed by evaluation of antimicrobial susceptibility pattern using Kirby Bauer disc diffusion method. Data were collected using a pretested structured questionnaire. Data were analyzed using SPSS programm, version 20.0.
resultsThe overall prevalence of bacterial UTIs was 11.6% (39/336). Escherichia coli was the predominant uropathogen (66.7%, 26/39), followed by Staphylococcus saprophyticus (17.9%, 7/39), Klebsiella pneumoniae (10.3%, 4/39), Proteus spp. (2.6%, 1/39), and Enterococcus faecalis (2.6%, 1/39). The highest UTI prevalence was observed among fifth-year students (23.53%), with borderline statistical significance (P = 0.054). Significant risk factors associated with UTIs included insufficient family monthly income (OR = 4.20, 95% CI: 1.26–14.03; P = 0.012), overcrowded living conditions (> 3 persons per sleeping room) (OR = 2.70, 95% CI: 1.31–5.55; P = 0.009), and the presence of other medical problems (OR = 2.93, 95% CI: 1.49–5.78; P = 0.001). The most common clinical symptoms among infected students were dysuria (33.33%) and cloudy urine (33.33%). Antimicrobial susceptibility testing revealed that all isolates (100%) were susceptible to gentamicin, while 79.49% were susceptible to levofloxacin and amikacin. High resistance rates were observed against ampicillin (51.28%), ciprofloxacin (51.28%), and doxycycline (46.15%).
conclusionThis study reveals a relatively low prevalence of UTIs among medical sciences students, with E. coli as the predominant pathogen. The findings highlight significant associations with socioeconomic factors and overcrowding, while the high resistance rates to commonly used antibiotics, particularly cefixime and ciprofloxacin, underscore the urgent need for antimicrobial stewardship programs and evidence-based treatment guidelines in this population.
