The plasma protein profile of left ventricular diastolic function.
Article in Scientific reports, 2026. 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
We aimed to characterize associations between plasma proteins and indices of left ventricular (LV) diastolic function in two population-based studies. Eighty-six cardiovascular-related plasma proteins measured by proximity extension assay (PEA) and echocardiography were assessed in the population-based studies PIVUS (n = 1,016; all aged 70) and POEM (n = 502; all aged 50). PIVUS served as the discovery cohort, and the Benjamini-Hochberg procedure was applied to control the false-discovery rate (FDR) < 0.05. POEM was used as the replication cohort. The protein panel was related to diastolic echocardiographic parameters. A larger protein panel of 1,322 proteins was examined only in POEM. Seven of 86 proteins showed replicated associations to the E/A ratio: CD40 ligand (CD40LG), proto-oncogene tyrosine-protein kinase Src (SRC), heat shock protein beta-1 (HSPB1), epidermal growth factor (EGF), TNF superfamily member 14 (TNFSF14), vascular endothelial growth factor D (VEGFD), and endothelial cell-specific molecule 1 (ESM1). Using the larger protein panel in POEM, 81 proteins showed significant associations with the E/A ratio, and five showed significant associations with LA diameter. Pathways linked to LV diastolic filling pattern were signal transduction, metabolic, disease and immune system pathways, enhancing the understanding of LV diastolic function and offering potential for future drug development.
