Impact of a patent ductus arteriosus on non-invasive pre- and post-ductal blood pressures in extremely preterm infants during the first two postnatal weeks.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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 evaluate pre- and post-ductal blood pressure (BP) in preterm infants according to patent ductus arteriosus (PDA) status obtained from targeted neonatal echocardiography (TnECHO). STUDY
designRetrospective cohort study of infants born at 22-28 weeks divided according to three groups: (i) No PDA, (ii) Low volume shunt, (iii) Moderate-high volume shunt. BP parameters, demographics, and clinical characteristics were compared.
resultA total of 373 TnECHOs were included: 98 no PDA, 152 low volume shunt, and 123 moderate-high volume shunt. TnECHOs with no PDA had higher systolic, diastolic, and mean BP. Diastolic flow reversal in the post-ductal descending aorta was associated with lower post-ductal diastolic (p < 0.001) and mean BP (p < 0.001). Moderate-high volume shunt had higher rates of diastolic hypotension.
conclusionBP patterns varied according to PDA status. Post-ductal hypotension was more common with a moderate-high volume shunt. PDA status in this population may be the strongest influencer of BP variability.
