Multidrug-resistant organism carriage in children admitted to a pediatric intensive care unit of a Greek tertiary hospital: prevalence and risk factors.
Article in Antimicrobial resistance and infection control, 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
backgroundAntimicrobial resistance is a global public health threat. Colonization with multidrug-resistant organisms (MDROs) often precedes infection and promotes transmission. However, data in pediatric populations remain limited. This study aimed to determine the prevalence of MDRO carriage among children admitted from the community to a Greek Pediatric Intensive Care Unit (PICU) and to explore associated risk factors.
methodsA cross-sectional study of children aged 0-16 years admitted to the PICU was conducted from January 1st to June 30th, 2024, excluding those hospitalized > 48 h or residing in care facilities. MDROs were identified from nasal, rectal, or bronchial secretion cultures collected within 48 h of admission. Epidemiological and clinical data were retrieved from medical records, and statistical analysis was performed to explore potential associations.
resultsOf 86 included children (median age 4.5 years, IQR 1-11; 53.5% male), 80 were screened within 48 h. MDRO colonization was identified in 18/80 patients (22.5%). ESBL-producing Escherichia coli (40.0%) and MRSA (20.0%) predominated. In exploratory multivariable analysis, lower absolute body weight (kg) was associated with MDRO carriage, with each 1 kg increase corresponding to approximately 18% lower colonization risk (OR = 0.818, 95% CI 0.680-0.984, P = 0.033), whereas no significant association was observed for weight-for-age.
conclusionsHigh rates of MDRO carriage in children admitted from the community to a PICU highlight an important public health concern and the need for enhanced preventive measures.
