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: Rheumatic mitral valve repair has been subject to clinical scrutiny due to the recurrence of postoperative regurgitation. This study aimed to identify factors associated with the development of mild or greater mitral regurgitation (MR) within 14 days after surgical repair. Methods: A total of 164 patients (mean age 44.73 years, 36 males) diagnosed with rheumatic mitral valve disease who underwent open-chest mitral valve repair at Shanghai Fourth People's Hospital, Tongji University School of Medicine, between March 17, 2023 and December 15, 2025, were enrolled. Mild MR was diagnosed using a comprehensive echocardiographic assessment, incorporating quantitative and semi-quantitative Doppler parameters-including color jet area (CJA) in the apical four-chamber view and vena contracta width (VCW), and the subjects were grouped accordingly. Results: A total of 164 patients were enrolled. Baseline clinical characteristics were well balanced between the two groups (all Conclusion: Preoperative CJA may serve as a valuable adjunctive parameter for perioperative risk stratification and individualized surgical planning in rheumatic mitral valve repair surgery.
