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
backgroundThe reliability of the recommended echocardiographic methods for assessing RV diastolic function has been questioned. We aimed to validate noninvasive indices of RV diastolic function, derived from tricuspid Doppler and myocardial deformation metrics, against intrinsic diastolic chamber properties and filling pressures.
methodsWe obtained simultaneous high-fidelity pressure-volume loops and echocardiographic data in separate animal and clinical settings: (1) a porcine model of acute hemodynamic interventions (n = 13), and (2) patients with Fallot tetralogy and pulmonary hypertension (n = 9). These designs allow for within- and between-subject validation. From the PV loops data, we obtained the reference values of RV stiffness (S
resultsIn the animal setting, only the tricuspid E/A ratio and e' velocity weakly correlated with S
conclusionsRecommended echocardiographic indices of RV diastolic function do not reflect intrinsic RV diastolic properties. Therefore, the application of these indices for inferring RV diastolic function and filling pressures is limited.
