Postnatal CMV Infection in Extremely Premature Newborns: A Single-Center Exploratory Study.
Article in Children (Basel, Switzerland), 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
BACKGROUND/
objectivesThe impact of postnatal CMV infection in extremely premature newborns is poorly characterized. We aimed to determine the impact and outcomes of postnatal CMV infection in a population of extremely premature newborns of gestational age of less than 29 weeks hospitalized in the Department of Perinatology, Division of Gynecology, University Medical Center Ljubljana.
methodsWe included all extremely premature newborns of gestational age of less than 29 weeks treated in the Department of Perinatology between December 2022 and December 2024. Newborns were screened for CMV infection at set timepoints and congenital infection was excluded with PCR testing. Additional PCR testing for CMV was performed if newborns developed clinical features suspect for postnatal CMV infection. Clinical characteristics and treatment outcomes of newborns were noted. Mothers of infected newborns had their CMV serostatus determined.
resultsIn total, 63 extremely premature newborns were included, and 14 newborns had confirmed postnatal CMV infection. Postnatal CMV infection was associated with hepatosplenomegaly and lower platelet and leukocyte counts compared to controls. We found no association between postnatal CMV infection and other neonatal comorbidities.
conclusionsIn our study, postnatal CMV infection was associated with a more severe and prolonged clinical course of extremely premature newborns compared to uninfected controls; however, in multivariable analysis, the association with a prolonged length of stay was no longer statistically significant. The results suggest that preventing postnatal CMV infection in this population is important.
