Development and validation of a nomogram to predict bronchopulmonary dysplasia in very preterm, very low birth weight infants.
Article in American journal of translational research, 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
objectivesThis study aimed to identify early predictors of bronchopulmonary dysplasia (BPD) in very preterm, very low birth weight infants and to construct and externally validate a nomogram that quantifies individual BPD risk shortly after birth to guide proactive clinical management.
methodsWe retrospectively analyzed 304 preterm infants admitted to our hospital between 2019-2024. The cohort comprised 113 infants diagnosed with BPD and 191 non-BPD controls. Clinical data, including maternal characteristics, neonatal parameters, and hematological indices measured at 14 days of postnatal age, were collected. Significant predictors of BPD were identified using logistic regression analysis and incorporated into a nomogram model for BPD risk assessment. The model's performance was externally validated using an independent cohort of 30 preterm infants admitted between January and June 2025.
resultsFactor analysis identified nine key BPD predictors (gestational age, birth weight, hypertensive disorders, neonatal respiratory distress syndrome, patent ductus arteriosus, blood transfusion, duration of nasal continuous positive airway pressure therapy, mean platelet volume, and white blood cell count), which were used to develop a BPD risk nomogram. The model demonstrated robust predictive performance, with area under the curve (AUC) values of 0.946 (95% CI: 0.927-0.966) for internal validation and 0.883 (95% CI: 0.750-0.989) for external validation, indicating a high discriminative ability.
conclusionThe results of this study provide an important basis for the early identification and management of BPD in premature infants and have potential clinical application value, which is helpful in improving the prognosis of children and optimizing the allocation of medical resources.
