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

backgroundRight ventricular (RV) function is closely associated with prognosis in isolated tricuspid regurgitation. Beyond conventional longitudinal indexes, nonlongitudinal RV deformation may provide additional prognostic information.

objectivesThe authors aimed to evaluate whether 3-dimensional (3D) RV circumferential strain (RV-CS) provides incremental prognostic value in patients undergoing isolated tricuspid valve surgery (ITVS).

methodsPatients scheduled for ITVS were prospectively enrolled and underwent 3D echocardiography 1 day before surgery. 3D RV longitudinal strain, CS, and area strain were derived using commercially available software. The primary endpoint was a composite of all-cause mortality or heart failure hospitalization.

resultsFrom April 2018 to December 2024, 251 patients were enrolled; 171/251 (68.1%) were women, and the mean age was 57 ± 14 years. During a median follow-up of 495 days, 48/251 patients (19.1%) reached the primary endpoint. Baseline 3D right ventricular circumferential strain (3D RV-CS) was lower in patients with events than in those without events (P < 0.001) and showed modest but had the highest Harrell's C-index for adverse events discrimination (0.695; 95% CI: 0.618-0.774; P < 0.001) among all tested RV function parameters. Patients with impaired 3D RV-CS, defined as |3D RV-CS| < 14%, had lower 1-year event-free survival than those with preserved 3D RV-CS (54.2% vs 92.5%; log-rank P < 0.001). After multivariable adjustment, impaired 3D RV-CS remained independently associated with adverse events. Adding 3D RV-CS improved risk reclassification beyond European System for Cardiac Operative Risk Evaluation II, TRI-SCORE, and Society of Thoracic Surgeons score models.

conclusions3D RV-CS provides complementary prognostic information in patients undergoing ITVS and may improve preoperative risk stratification.
