Changes in left ventricular systolic function after transcatheter patent ductus arteriosus closure in premature infants.
Article in Annals of pediatric cardiology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Changes in left ventricular (LV) systolic function have not been well described in premature neonates after transcatheter patent ductus arteriosus (PDA) closure. Methods and Results: We retrospectively identified all premature neonates < 3 kg who underwent a transcatheter PDA closure at our center between January 1 2015 and January 31, 2021. LV indices before and after closure were extracted and an analysis was performed. Overall, 23 neonates were included with a mean procedural weight of 1894 ± 622 g. At 24 h after closure, the median left ventricular ejection fraction (LVEF) (66% interquartile range [IQR] 12% vs. 61% IQR 12, Conclusion: In preterm neonates who underwent successful transcatheter PDA closure, 23% developed abnormal LVEF after closure and those with significant LV dilation before the procedure were at increased risk for the development of LVEF <55% after closure.
