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: Geometric alterations in the tricuspid annulus (TA) are common in atrial functional tricuspid regurgitation (A-FTR), and may reflect structural and dynamic changes that contribute to disease severity. Methods and results: Comprehensive two-dimensional and 3D echocardiographic analyses were performed in 216 patients with A-FTR. Geometric parameters included indexed TA area, sphericity index, and tenting volume. Dynamic parameters included TA area fraction, TA excursion, and unfavourable TA dynamics. A-FTR groups. Indexed TA area and tenting volume increased significantly with A-FTR severity (all Conclusion: 3D remodelling and unfavourable TA dynamics independently correlated with A-FTR severity. TA geometry was linked to RA volume, while dynamics reflected RV remodelling. These findings support a potential sequential mechanism, highlighting the value of comprehensive 3D assessment.
