Predictive Value of Viable Myocardium of Papillary Muscle-Ventricular Wall Complex for Improvement in Moderate Ischemic Mitral Regurgitation.
Article in CJC open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Performing a mitral valve procedure during coronary artery bypass grafting (CABG) in patients with coronary artery disease complicated by moderate ischemic mitral regurgitation (IMR) remains controversial. This study aimed to assess the benefit of isolated CABG and to develop a new index of viable myocardium within the papillary muscle-ventricular wall complex (VM-PM-VWC) to predict the improvement of IMR by CABG alone. Methods: In total, 122 patients (age, 62.34 ± 8.53 years; 78.70% male) with moderate IMR who underwent CABG alone at Beijing Anzhen Hospital were retrospectively analyzed. All patients underwent Results: The VM-PM-VWC was an independent factor for moderate IMR improvement (odds ratio, 1.16; 95% confidence interval [CI], 1.09-1.24; Conclusions: Most patients with moderate IMR improved from isolated CABG. The VM-PM-VWC was an independent predictor of IMR improvement, which could help surgical decision making. Clinical Trial Registration: ChiCTR2100042454.
