Clinical analysis and predictive value of early serum lipid levels in very premature and extremely preterm infants with bronchopulmonary dysplasia: a 4 years retrospective study.
Article in BMC pediatrics, 2025. 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
backgroundLipid metabolism plays an important role in fetal growth and development, but its role in lung maturation is currently unknown. We investigated the relationship between early serum lipid levels and clinical characteristics of bronchopulmonary dysplasia (BPD) in very preterm and extremely preterm infants.
methodsThis study analyzed the clinical data of preterm infants with gestational age ≤ 32 weeks between January 2020 and February 2024, while clinical risk factors, maternal comorbidities, treatment methods and prognosis were retrospectively reviewed for subjects (n = 341) recruited from neonatal intensive care unit (NICU).
resultsOf 228 BPD and 113 non-BPD extremely preterm infants, univariate analysis found that triglyceride (TG, P < 0.01) and high-density lipoprotein (HDL, P = 0.04) levels on the first day of admission were significantly lower in BPD infants, however, apolipoprotein A1 levels were higher than those in the non-BPD group (P < 0.01). Multivariable model further revealed that apolipoprotein A1 (Apo-A1) was a dominant determinant (OR 6.55, 95% CI 2.61,6.12). Regarding perinatal risk factors, maternal gestational hypertension was a risk factor for the morbidity of BPD (P = 0.04), while prenatal hormone exposure displayed a positive performance (P = 0.01). Kaplan-Meier curve showed no statistical difference in survival between low and normal serum lipid level groups (P > 0.05).
conclusionsTG, HDL, Apo-A1 levels provide an insight risk and prognostication stratification in very preterm BPD infants, thus, neonatologists should emphasize high-risk features and optimize preventive therapy.
