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 Atrial fibrillation (AF) is a common arrhythmia associated with high morbidity and mortality. While the left atrial volume index (LAVI) is a known prognostic marker, the right atrial volume index (RAVI) in this setting remains less well defined. This study aimed to investigate the incremental prognostic value of the RAVI alongside the LAVI in predicting adverse cardiovascular outcomes in patients with AF, a common arrhythmia associated with increased morbidity and mortality. MATERIAL AND METHODS A retrospective cohort study was conducted involving 421 patients with non-valvular AF. Patients were classified based on the occurrence of adverse events, including hospitalization for heart failure, stroke, and all-cause mortality. Echocardiographic assessments of LAVI and RAVI were performed according to international guidelines. RESULTS Among the 421 patients, 180 (43%) experienced adverse events. Enlargement of both LAVI and RAVI was significantly associated with death, stroke, and heart failure (P<0.001). In multivariate analysis adjusted for age and sex, LAVI and RAVI were independent predictors of adverse outcomes. The presence of either LAVI or RAVI enlargement was associated with increased mortality (HR=1.96, 95% CI: 1.17-3.31), while the combined enlargement of both indices further increased the risk (HR=4.38, 95% CI: 2.71-7.08). Similar patterns were observed for stroke and heart failure, where the combination of both enlarged indices significantly amplified risk. CONCLUSIONS RAVI adds significant incremental prognostic value to LAVI in patients with AF. Combined assessment of both atrial volume indices enhances risk stratification for heart failure, stroke, and mortality, supporting more personalized treatment approaches in clinical practice.
