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
backgroundTricuspid regurgitation (TR) progression is a recognized complication following permanent pacemaker (PPM) implantation with a significant impact on morbidity and mortality. The role of procedural aspects as well as advanced echocardiographic parameters in predicting TR progression remains incompletely defined.
objectiveTo investigate procedural factors and echocardiographic parameters predicting progression to moderate-to-severe TR following PPM implantation.
methodsFifty-two consecutive patients undergoing PPM implantation were prospectively included. Conventional echocardiography and speckle-tracking echocardiography (STE) were performed at baseline, 3 months, and 6 months post-implantation. Patients were classified according to the development of moderate-to-severe TR during follow-up.
resultsModerate-to-severe TR developed in 17 patients (32.7%) during follow-up. Baseline clinical and echocardiographic parameters were largely comparable between groups, although patients with subsequent TR progression had mildly impaired baseline RV free wall longitudinal strain (RV-FWLS) (p = 0.04). At 3 months, patients with TR progression demonstrated worse RV-FWLS (p = 0.01), higher RV dyssynchrony index (p = 0.02), and larger tricuspid annular diameter (p = 0.04). On multivariable analysis, the direct trans-tricuspid crossing technique (OR 5.42, 95% CI 1.01-29.12; p = 0.048), ventricular pacing burden (OR 1.39, 95% CI 1.05-1.86; p = 0.02), 3-month RV-FWLS (OR 1.47, 95% CI 1.01-2.15; p = 0.04) and 3-month RV dyssynchrony index (OR 1.54, 95% CI 1.02-2.31; p = 0.03) could independently predicted TR progression. ROC analysis showed good predictive performance for RV dyssynchrony index (AUC 0.86) and RV-FWLS (AUC 0.83).
conclusionsEarly abnormalities in RV strain and mechanical dyssynchrony were associated with subsequent TR progression following PPM implantation, highlighting the potential value of advanced echocardiographic assessment for early risk stratification.
