Trajectory of lung ultrasound scores in preterm infants at risk for bronchopulmonary dysplasia.

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 quantify the trajectory of lung ultrasound scores (LUSSc) and estimate their association on inpatient respiratory trajectories in preterm infants with potentially evolving bronchopulmonary dysplasia (BPD) STUDY
designWe measured LUSSc prospectively in infants <32 weeks' gestation weekly from 2 weeks of life through 44 weeks' post-menstrual age (PMA) or discharge. The primary outcome was the age, in PMA, to achieve liberation of respiratory support (LRS) defined as room air or < 1 L/min (F
resultIn 16 infants, 10 patients had Grade 2-3 BPD, and LUSSc declined over time. The median age to achieve LRS was 42 weeks' PMA (33.6, 47.9). Using the maximum LUSSc each infant had between 30 and 32 weeks' PMA, each 1-point increase in the LUSSc was independently associated with a 9-day increase in the age to achieve LRS.
conclusionLUSSc may serve as a diagnostic marker for inpatient respiratory trajectories of preterm infants with evolving BPD.
