Characteristics and outcomes of preterm infants with pulmonary vein stenosis in the contemporary era: a PHIS database analysis.
Article in Journal of perinatology : official journal of the California Perinatal Association, 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
backgroundPulmonary vein stenosis (PVS) is increasingly recognized in preterm infants, yet data regarding characteristics and outcomes remain limited.
methodsA review of hospitalizations from 50 children's hospitals across the United States participating in the Pediatric Health Information System (PHIS) database was performed. We identified 268,461 pediatric patients (≤24 months of age) with a history of prematurity (<37 weeks' gestation) admitted between 2016 and 2024. PVS was identified in 703 (0.3%) using ICD-10 diagnosis code I28.8.
resultsBronchopulmonary dysplasia, birthweight ≤1.5 kg, Oxygen and ventilator dependency at discharge, pulmonary hypertension, left-to-right shunt lesions, and necrotizing enterocolitis were associated with PVS. Interestingly, gestational age <28 weeks was not associated with PVS. Patients with PVS had higher in-hospital mortality (11.4% vs 2%, p < 0.01), longer hospitalization, and substantially higher adjusted hospitalization costs. After adjusting for prematurity and comorbidities, PVS remained associated with in-hospital mortality (OR 4.3, 95% CI 3.4-5.5, p < 0.01).
conclusionPVS in preterm infants is associated with in-hospital mortality, morbidity, and resource utilization, highlighting the need for improved recognition and structured surveillance.
