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
introductionreduced exercise capacity, coronary artery abnormalities and reversible myocardial ischemia have been demonstrated after arterial switch operation (ASO) and coronary reimplantation. Despite this, indices of systolic function, assessed by standard and Doppler echocardiography, are within the normal range. The aim of this study was to highlight the long-term changes in myocardial function following coronary reimplantation using Doppler and speckle-tracking imaging (STI) echocardiography.
methodsthis observational case control study included 36 patients and 20 gender and age-matched healthy controls. A group study was performed using patients who were followed for at least 6 months after the operation and who visited the pediatric cardiology outpatient between October 2015 and May 2016. Systolic and diastolic parameters, left ventricle (LV) and right ventricle (RV) myocardial performance were assessed in each group.
resultsthe LV global peak strain parameters revealed a significant decrease in the longitudinal and circumferential strain components. The LV global longitudinal strain (GLS) values were lower in both groups of operated patients than controls (-19.9 ± 2.2% (group 1) versus -20.9 ± 1.6% (group 2) versus -22.9 ± 2.3% (group 3), p<0.001). The patients with coronary reimplantation had the lowest values. The LV global circumferential strain was also decreased in the group 1 patients as compared with the 2 other groups (-16.6 ± 4.1% (group 1) versus -19.4 ± 3.9% (group 2) versus -19.8 ± 4.0% (group 3), p<0.001).
conclusionalthough global LV function, assessed with conventional echocardiographic parameters, was normal, the 2D-STI analysis showed slight but significant decrease in the global and segmental longitudinal and circumferential LV strain during the long-term follow-up after coronary arteries reimplantation.
