Follow-Up Report of Patients With Moderate Aortic Valve Regurgitation After Cardiac Surgery.
Article in Texas Heart Institute journal. 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: The appropriateness of aortic valve surgery for patients with moderate aortic valve regurgitation undergoing coronary artery bypass graft (CABG), mitral valve replacement (MVR), or both is uncertain. This study aimed to investigate the outcomes of moderate aortic valve regurgitation following these procedures. Methods: This retrospective cohort study included 113 eligible participants with moderate aortic valve regurgitation who underwent CABG, MVR, or both procedures between January 2014 and January 2015 at Tehran Heart Center. Echocardiographic index data were extracted from the Tehran Heart Center data center after a 2-year follow-up to examine changes in the patients' conditions. Results: A total of 113 patients (mean [SD] age, 64.7 [9.9] years; 78 [69.0%] female patients) were included in the study and followed up for a mean (SD) of 24 (6) months. Among those patients, 38 (33.6%) experienced improvement, with their aortic valve regurgitation downgraded to mild, while the remaining 75 (66.4%) patients maintained a moderate aortic valve regurgitation level. Notably, combined CABG and MVR procedures were associated with statistically significant improvement, with all cases downgraded to mild aortic valve regurgitation. Baseline characteristics, including diabetes, hypertension, dyslipidemia, smoking, family history of aortic valve regurgitation, and a history of drug use, did not differ statistically significantly between patients with improved aortic valve regurgitation and patients with no changes. Echocardiographic indices related to the aorta, such as aortic valve pressure gradient, showed improvement ( Conclusion: These findings suggest that it is not likely that moderate aortic valve regurgitation will progress after CABG or MVR. Hence, no support was found for concurrent aortic valve replacement during these procedures.
