Gut Pathogen Colonization: A Risk Factor to Bloodstream Infections in Preterm Neonates Admitted in the Neonatal Intensive Care Unit - A Prospective Cohort Study.
Article in Neonatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionGut pathogen colonization, where pathogens disrupt the normal gut microbiota, has been implicated in the development of bloodstream infections (BSIs). This study investigates the association between gut pathogen colonization and BSI, hypothesizing that species causing BSI primarily originated from gut.
methodsA prospective cohort study was conducted in the neonatal intensive care unit (NICU) of tertiary care hospital in Karnataka, India, from January 2021 to September 2023. Inborn preterm infants were enrolled. The study population was divided into two groups: group A (neonates without sepsis) and group B (neonates with sepsis). Demographic details and blood culture results were collected. Stool samples were taken on day 4 and day 14 for group A, and on day 4 and the day of sepsis diagnosis for group B.
resultsGroup B had a lower mean birthweight (1,649.6 ± 652.1 g) compared to group A (1,757 ± 656 g). Klebsiella pneumoniae was the most common pathogen causing BSIs (44.1%). The analysis revealed a high abundance of potential pathogens in the gut microbiome of group B neonates, with a concurrent decrease in beneficial gut flora.
conclusionThis study provides strong evidence for the association between gut pathogen colonization and BSI development in preterm neonates in NICUs. Gut microbiota modulation may serve as preventive strategy against BSIs, emphasizing the need for further research in this area to improve outcomes in vulnerable population.
