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
Background: The diagnostic utility of transthoracic echocardiographic Doppler parameters in differentiating between normal and abnormal function of the mechanical prosthetic tricuspid valve (MPTV) has not been thoroughly investigated. This study aimed to evaluate the diagnostic accuracy and determine the optimal cutoff values of Doppler parameters in the detection of MPTV dysfunction. Methods: We retrospectively analyzed 91 patients who underwent MPTV replacement over the past 12 years. The study cohort was divided into two groups: an experimental group consisting of 15 patients with 16 separate episodes of MPTV dysfunction, and a control group comprising 76 patients with normal leaflet function. Doppler parameters were measured at the tricuspid valve (TV) position included pressure half-time (PHT Results: Compared to the control group, patients with MPTV dysfunction exhibited significantly higher values for PHT Conclusions: The study highlights the significant diagnostic utility of transthoracic echocardiographic Doppler parameters in identifying MPTV dysfunction.
