Clinical profiles and modifiable risk factors for catheter-associated urinary tract infections in hospitalized obstetrics and gynecology patients: a case-control study.
Article in BMC infectious diseases, 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) impose significant clinical and economic burdens on healthcare systems globally. Patients in obstetrics and gynecology face unique vulnerabilities; however, population-specific risk factors and prevention strategies remain inadequately studied from a public health perspective.
objectiveThis study aimed to identify clinical profiles and modifiable risk factors for CAUTIs in hospitalized obstetrics and gynecology patients, thereby informing evidence-based CAUTI prevention strategies.
methodsA retrospective case-control study was conducted among inpatients at the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China, from November 2021 to February 2024. The case group comprised all consecutive eligible patients (n = 131) with symptomatic CAUTIs. Controls (n = 131) were matched to cases at a 1:1 ratio based on hospitalization period, primary diagnosis, treatment type, and age (± 5 years). Multivariate logistic regression analyses were performed to identify independent risk factors.
resultsMultivariate analysis of 262 obstetrics and gynecology inpatients identified four modifiable risk factors for CAUTIs, including being nutritionally at-risk upon admission (OR = 4.189, 95% CI: 1.402 ~ 12.513, P = 0.010), discharge with an indwelling urinary catheter (OR = 5.526, 95% CI: 2.352 ~ 12.985, P < 0.001), multiple catheterizations (≥ 2) (OR = 16.642, 95% CI: 2.057 ~ 134.617, P = 0.008), and a hospital stay exceeding 7 days (OR = 2.547, 95% CI: 1.423 ~ 4.560, P = 0.002). Fever was the predominant clinical symptom (85.5%), and Escherichia coli was identified as the primary pathogen (59.4%).
conclusionTargeted public health interventions should prioritize nutritional screening, catheter minimization protocols, standardized discharge planning for catheterized patients, and the reduction of prolonged hospitalizations. Healthcare policy must integrate these evidence-based strategies to mitigate the burden of CAUTIs in women’s health settings.
