Left ventricular diastolic dysfunction in preterm infants with 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
introductionEchocardiographic algorithm based assessment of diastolic function during neonatal period could help in early identification of left ventricular diastolic dysfunction (LVDD) in infants with bronchopulmonary dysplasia (BPD).
aimTo screen infants with BPD at 36 weeks postmenstrual age for LVDD.
methodsWe used conventional Doppler and myocardial deformation parameters suggested in the latest American Society of Echocardiography algorithm to evaluate LV function. Tricuspid-regurgitation velocity, LV shape, LV eccentricity and pulmonary ejection pattern were used to diagnose pulmonary hypertension (PH). The algorithm was then followed using age appropriate cut-off values to identify and grade LVDD.
resultsScans of 71 control infants and 93 infants with BPD were analysed. We noted PH in 15% infants with BPD and 7% control infants. Grade 2 LVDD was seen in 5% infants with BPD compared to 1.4% control infants.
conclusionRate of PH and grade 2 LVDD was significantly higher in infants with moderate to severe BPD.
