Recent Trends in Achievement Rates and Time Required for Left Ventricular Reverse Remodeling in Dilated Cardiomyopathy.
Article in Circulation reports, 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: Left ventricular reverse remodeling (LVRR) is associated with a good prognosis in patients with dilated cardiomyopathy (DCM), so in this study we examined the achievement rates of LVRR, the time taken to LVRR and the factors associated with LVRR in recent cases of DCM. Methods and Results: We enrolled 121 patients with DCM. LVRR was defined as a left ventricular ejection fraction ≥40% at follow-up with a ≥10% improvement. LVRR was observed in 82 patients (68%). The median time to LVRR was 208 days. Multivariate analysis revealed that B-type natriuretic peptide (BNP) levels at discharge (per 1-SD increase, odds ratio: 0.483, 95% confidence interval (CI): 0.224-0.963; P=0.0385) and β-blocker dose (per 1-SD increase, odds ratio: 3.379, 95% CI: 1.644-7.702; P=0.0007) were independently associated with LVRR. When the patients were divided into 2 groups according to the first (2007-2017; n=64) and second (2018-2022; n=57) time periods, there was a significantly higher LVRR achievement rate (48.4% vs. 89.5%) and shorter time to LVRR in the second period than in the first. Conclusions: The LVRR achievement rate in DCM has been increasing, and the time to LVRR has been shortened in recent years. Beta-blocker dose and BNP levels at discharge may be strongly associated with LVRR.
