1 · What the graph read from it

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.

2 · The registry

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: Tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP) is an established prognostic marker in tricuspid regurgitation (TR). Right ventricular free wall longitudinal strain (RVFWS)/PASP has been proposed as more sensitive prognostic markers than TAPSE/PASP in patients with TR, yet its role in patients undergoing transcatheter tricuspid valve repair (TTVr) remains unclear. The objective of the study was to evaluate and compare the prognostic value of RVFWS/PASP and TAPSE/PASP with two different vendors in symptomatic TTVr cohorts. Methods: TTVr-treated patients across three centers (2017-2023) were included. RVFWS was assessed using two vendors (A = GE EchoPAC and B = Tomtec). The primary endpoint was a composite of all-cause mortality or the first heart failure hospitalization at 2-years. Prognostic performance was assessed using Cox regression, C-statistics, and Kaplan-Meier analysis. Results: A total of 349 patients were included (137 vendor A and 212 vendor B). Patients in vendor B were older (83 vs. 80; Conclusions: Both RVFWS/PASP and TAPSE/PASP provided modest prognostic value after TTVr, with TAPSE/PASP demonstrating consistent independent association across vendors.
