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
backgroundRight ventriculo-pulmonary artery (RV-PA) coupling, commonly assessed by the ratio of tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), has emerged as an important prognostic marker in various cardiovascular diseases. However, its predictive value after transcatheter aortic valve implantation (TAVI) remains insufficiently defined. This study aimed to evaluate whether postoperative TAPSE/PASP is independently associated with long-term all-cause mortality in patients undergoing transfemoral TAVI.
methodsWe retrospectively analyzed 786 consecutive patients who underwent transfemoral TAVI between June 2020 and March 2025. Postoperative TAPSE/PASP was measured within the first week after the procedure. Receiver-operating characteristic (ROC) curve analysis determined the optimal TAPSE/PASP cut-off for predicting long-term mortality. Survival analyses were performed using the Kaplan-Meier method and Cox proportional hazards regression.
resultsDuring a median follow-up of 509 days (interquartile range: 283-847), 61 patients (9.0%) died. Receiver-operating characteristic (ROC) analysis identified 0.52 mm/mmHg as the optimal postoperative TAPSE/PASP cut-off (AUC = 0.626, P < .001, 95% CI: 0.57-0.68). Patients with TAPSE/PASP <0.52 (n = 278) had worse clinical, echocardiographic, and laboratory profiles than those with TAPSE/PASP ≥0.52 (n = 508). Kaplan-Meier analysis demonstrated significantly reduced survival in the lower TAPSE/PASP group (12.6% vs. 5.1% mortality, log-rank P < .001). In multiple Cox regression, age (HR = 1.044, P = .044, 95% CI: 1.001-1.089), chronic obstructive pulmonary disease (COPD) (HR = 2.261, P = .012, 95% CI: 1.192-4.290), and postoperative TAPSE/PASP (HR = 0.856 per 0.1 mm/mm Hg increase, P = .033, 95% CI: 0.743-0.988) remained independent predictors of long-term mortality.
conclusionsLower postoperative TAPSE/PASP (<0.52 mm/mmHg) is independently associated with increased long-term mortality after TAVI, supporting its use for early postoperative risk stratification.
