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: This study aims to compare the mid-term clinical and echocardiographic outcomes of quadrangular resection (QR) and butterfly resection (BR) techniques in patients with isolated posterior leaflet prolapse and/or chordal rupture due to Barlow's disease. Methods: Between May 2009 and January 2023, a total of 142 patients (89 males, 53 females; mean age: 56.6±11.9 years; range, 20 to 84 years) who underwent mitral valve repair with either QR (n=69) or BR (n=73) were retrospectively analyzed. Patients were evaluated using transthoracic and transesophageal echocardiography preoperatively, intraoperatively, and during mid-term follow-up. Clinical variables, echocardiographic parameters, and surgical data were compared between groups. Results: Baseline characteristics and preoperative echocardiographic findings were similar between the two groups. Both techniques resulted in significant improvements in the New York Heart Association functional class, mitral regurgitation severity, and left ventricular dimensions. However, the BR group demonstrated significantly improved posterior leaflet mobility (Wilkins score 1.97±0.74 Conclusion: Butterfly resection is a technically feasible, effective, and anatomically favorable technique for mitral valve repair in Barlow's disease. Its ability to preserve leaflet mobility and minimize mitral gradients makes it a valuable addition to the surgical armamentarium, particularly in anatomically complex cases.
