Perinatal risk factors for hemodynamically significant patent ductus arteriosus in very low birth weight infants.
Article in Clinical and experimental pediatrics, 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
backgroundMultiple perinatal factors influence hemodynamically significant patent ductus arteriosus (HS PDA) in preterm infants. PURPOSE: This study aimed to identify the risk factors associated with HS PDA in very low birth weight infants (VLBWIs) and determine the predictors of surgical ligation.
methodsThis retrospective study included VLBWIs born at 23-32 weeks' gestation whose HS PDA properties could be identified using echocardiography. The infants were stratified into 2 groups based on gestational age (23-27 and 28-32 weeks).
resultsAmong the 496 included VLBWIs, 171 had no PDA, 90 had non-HS PDA, and 235 had HS PDA. In infants born at 23-27 weeks' gestation, risk factors for HS PDA included low birth weight, the absence of histological chorioamnionitis, and premature rupture of membranes. For VLBWIs born at 28-32 weeks' gestation, HS PDA was associated with lower birth weight, frequent surfactant treatment, and maternal hypertension. Within the HS PDA group, infants with a lower birth weight or who received incomplete antenatal steroid administration had an increased likelihood of requiring surgical ligation, whereas those with a small-for-gestational-age status had a decreased need for surgical ligation.
conclusionRecognizing these risk factors can aid the development of targeted treatment strategies for HS PDA in VLBWIs, enabling early ligation and potentially reducing the need for surgical management.
