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
backgroundIncreased aortic stiffness in patients with bicuspid aortic valve (BAV) may significantly affect morbidity and mortality.
objectiveWe aimed to evaluate aortic elasticity properties and the usability of the new technique by measuring pulse wave velocity (PWV) with a transthoracic echocardiography device in patients with BAV.
methodsFifty patients with BAV and 50 healthy children with similar demographic characteristics were included in this study. Patients with BAV were grouped according to fused cusp morphology. Valve function was normal or near normal in the patients with BAV included in the study. All patients' left ventricular function, aortic root diameter, and aortic elasticity characteristics were evaluated. A p-value <0.05 was considered significant.
resultsPWV was significantly higher in the BAV group (p=0.000). Aortic elasticity parameters obtained from ascending aorta diameters were similar between the groups. Ascending aorta diameters were significantly higher in the BAV group. There was a correlation between PWV, ascending aortic diameter, vena contracta in aortic regurgitation, and peak aortic velocity. PWV inter- and intraobserver reliability alpha values were 0.92 and 0.84, respectively.
conclusionsIn the pediatric BAV group with normal or near-normal valve function, although aortic elasticity parameters were normal with conventional measurements based on ascending aorta diameters, PWV measurements with the same device were significantly higher without the need for an additional apparatus or program, and aortic stiffness increased in the BAV group. PWV measurement by echocardiography is a reliable and reproducible technique.
