Clinical, laboratory, and microbiological differences between early- and late-onset neonatal sepsis in preterm infants: a cross-sectional study in Vietnam.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAlthough neonatal sepsis remains a significant cause of morbidity and mortality in preterm infants, few studies in Vietnam have compared the characteristics of early-onset sepsis (EOS) and late-onset sepsis (LOS).
objectiveTo compare the clinical, laboratory, and microbiological characteristics of EOS and LOS in preterm neonates at a tertiary obstetric hospital in Vietnam.
methodsThis cross-sectional study included 106 preterm infants with culture-confirmed sepsis admitted from August 2022 to May 2024. Clinical data, laboratory results and blood cultures were analyzed. Statistical tests and univariate logistic regression were used to explore differences between EOS and LOS.
resultsOf 106 neonates, 24 (22.6%) had EOS, and 82 (77.4%) had LOS. LOS predominated in extremely preterm, very low birth weight infants and was associated with more severe symptoms, including respiratory distress and abnormal heart rate. EOS cases were more likely to have birth weight ≥ 1500 g and maternal conditions such as intrapartum fever, genital infections, contaminated amniotic fluid and prolonged amniotic fluid leakage (> 18 h). Laboratory analysis revealed higher levels of leukopenia, platelet and cerebrospinal fluid protein in EOS, as well as elevated C-reactive protein and blood protein in LOS. Gram-negative bacteria were predominant in both groups. Escherichia coli was most common in EOS (46%), whereas Klebsiella pneumoniae predominated in LOS (38%).
conclusionEOS and LOS in preterm neonates exhibit distinct patterns in perinatal factors, clinical manifestations, laboratory findings and microbiological profiles. Differentiating these two entities may aid in timely diagnosis and guide empirical treatment in settings with limited resources.
