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
Aims: Myocardial stiffening naturally occurs with aging and contributes to diastolic dysfunction. Assessing myocardial stiffness non-invasively could improve the sensitivity of diastolic function evaluation in clinical practice. Shear wave (SW) elastography is a non-invasive tool for quantifying myocardial stiffness, where higher SW velocities indicate increased stiffness. We investigated whether SW elastography could detect differences in myocardial stiffness between athletes and sedentary non-athletes and, during exercise, reveal differences in operational stiffness that may indicate diastolic dysfunction. Methods and results: We enrolled 20 master athletes (median age 60 [IQR 59-66] years) and 17 sedentary non-athletes (median age 58 [IQR 52-71] years). Standard exercise echocardiography revealed no significant differences in diastolic function between the groups. Additionally, ultra-high frame rate imaging was used to measure SW velocities after mitral valve closure (MVC) and aortic valve closure (AVC) at rest and during exercise. At rest, athletes had lower SW velocities after MVC compared to sedentary non-athletes (3.2 ± 0.4 m/s vs. 3.9 ± 0.7 m/s, respectively, Conclusion: SW elastography reveals reduced myocardial stiffness in athletes compared to sedentary non-athletes at rest and during exercise, which is not detected by conventional echocardiographic measurements. Exercise-induced changes in SW velocities after AVC may potentially serve as an early marker for detecting diastolic dysfunction.
