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
Introduction: Tricuspid regurgitation (TR) is associated with high rate and poor prognosis in patient undertreated. In recent years, transcatheter tricuspid valve interventions (TTVI) appears like a valuable option in high risk surgical candidates in presence of suitable anatomy. Screening phase with transthoracic, thansoesophageal echocardiography, and cardiac computed tomography (CT) are necessary select patients. Purpose: The aim of the study is to compare different imaging modalities as three-dimensional (3D) transthoracic echocardiography (TTE), transesophageal echocardiography (TOE) and ECG-gated cardiac CT for the definition of tricuspid valve (TV) function and geometry assessment. Materials and Methods: Twenty-one (age 79 ± 7 years, female 72%) patients under screening for transcatheter treatment of TR were prospectively enrolled in the study and underwent TTE, TOE, and cardiac CT. All measurements were performed in double blind by three different operators and compared. Results: In the comparison between 2D/3D TTE and 2D/3D TOE, no statistically significant differences were found regarding the evaluation of the valve anatomy, the site of regurgitation, and the underlying mechanism (TTE vs. TOE: 3D septo-lateral diam 45.8 ± 4,92 vs. 45.87 ± 4,98 mm, Conclusions: The present series shows how a lone 3D TTE has a good reliability in the definition of TV function, leaflet characteristics, and geometry when compared with second level imaging modalities and may be safely used to select optimal candidates for complex TTVI.
