Long-term outcomes in adults born preterm with symptomatic patent ductus arteriosus.
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
objectiveTo compare outcomes in young adults born prematurely with and without symptomatic patent ductus arteriosus (PDA) during infancy. STUDY
designYoung adults born preterm (≤32 weeks gestation; n = 107) were recruited from the Parkland Health Neonatal Intensive Care Unit (NICU) Registry and compared based on presence of symptomatic PDA during their NICU stay (n = 23 with PDA), defined as clinical evidence of large left-to-right shunt or congestive heart failure.
resultsSystolic blood pressure was similar, but the PDA group exhibited higher resting diastolic blood pressure (80 ± 10 versus 74 ± 12 mmHg, p = 0.02). Biventricular systolic function was similar. However, tissue Doppler imaging (TDI) velocities at the lateral/septal aspect of the mitral annulus were lower and RV end-diastolic diameter larger in the PDA group.
conclusionsIndividuals born preterm with a symptomatic PDA exhibited elevated diastolic blood pressure, slightly lower diastolic function, and larger right ventricular size in early adulthood.
