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: Electrocardiography (ECG) in patients with mitral stenosis (MS) reveals characteristic findings, including altered P-wave morphology, reflecting left atrial (LA) hemodynamic changes. This research focused on the relationship between ECG parameters and LA hemodynamics in patients with severe MS. Methods: A cross-sectional retrospective study was conducted on 42 patients undergoing Percutaneous Transluminal Mitral Commissurotomy at Shafa Hospital, Kerman, Iran. ECG parameters, echocardiographic measurements, and angiographic findings were analyzed to assess associations between P-wave morphology and LA hemodynamic variables. Results: Significant correlations were found between LA volume and P-wave duration, amplitude, area, and terminal force in lead V1 ( Discussion: The present study highlights a significant correlation between P-wave morphology in the ECG and LA volume. Notably, the relationship between Conclusion: ECG parameters, particularly P-wave morphology, exhibit significant associations with LA volume in severe MS patients. These findings suggest the potential utility of ECG as a cost-effective tool for assessing LA volume and identifying patients who may be at risk for atrial fibrillation in MS.
