Longitudinal systolic strain of the bilayered ventricular septum during the first 72 hours of life in preterm infants.
Article in Journal of echocardiography, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundQuantitative evaluation of right ventricular myocardial performance in preterm infants remains a challenge because of the limitations of conventional echocardiographic measurement and the complex geometry of the right ventricle (RV). Serial assessment of peak longitudinal systolic strain on the right and left sides of the ventricular septum (VS), RV, and left ventricle (LV) during the transitional period in preterm infants using two-dimensional speckle-tracking echocardiography is reported.
methodsIn 21 preterm infants (33 ± 2 gestational weeks, 1,913 ± 218 g birth weight) without mechanical ventilation, inotropic agents, or symptomatic patent ductus arteriosus (PDA), longitudinal strain (LS) was measured on both sides of the VS, RV free wall, and LV, along with conventional echocardiography at 1, 3, 6, 9, 12, 24, 48, and 72 h after birth. Correlations and factors associated with echocardiographic measurements were analyzed.
resultLS was maintained on the four analyzed regions during the first 72 h of life despite significant hemodynamic changes, including a decrease in pulmonary artery pressure and PDA closure. LS was significantly larger on the left side of the VS than on the right side of the VS at 1, 48, and 72 h after birth.
conclusionsPreterm infants showed stable LS on both sides of the VS, the RV free wall, and the LV despite significant hemodynamic changes during the first 72 h of life. These results suggest that the right and left sides of the VS respond differently to the complex cardiopulmonary transitions from fetal to neonatal life in preterm infants.
