B-type Natriuretic Peptide Changes and Left Ventricular Remodeling Dynamics in Heart Failure with Reduced Ejection Fraction.
Article in medRxiv : the preprint server for health sciences, 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: B-type natriuretic peptide (BNP) is an important biomarker in heart failure with reduced ejection fraction (HFrEF). We aimed to explore changes in BNP and their relationship with long-term dynamics of left ventricular (LV) geometry. Methods: This was a single-center retrospective cohort. Inclusion criteria included LV ejection fraction (LVEF) <40% measured by echocardiography, BNP ≥100 pg/mL at baseline, and a subsequent BNP measure within a year. Percent BNP change from baseline was computed and divided into tertiles. Tertiles represented decreasing, minimal changes, and rising BNP levels. The study endpoint included LV internal dimension at end-systole (LVIDs), LV internal dimension at end-diastole (LVIDd), and LVEF. The secondary endpoint consisted of all-cause mortality. Results: A total of 887 patients were included. Baseline characteristics, including age, sex, blood pressure, atrial fibrillation, baseline BNP, and LVEF, varied among tertiles (p<0.05). When comparing to the rising BNP tertile, the decreasing BNP tertile showed decreased trends of LVIDs (p=0.001), LVIDd (p=0.006); and increased trends of LVEF (p=0.008). All-cause mortality was higher in the rising BNP tertile (p<0.05) compared to the decreasing tertile. Conclusion: In a real-world routine HFrEF cohort, this study demonstrates the
