Proteome-Wide Mendelian Randomization Identifies Natriuretic Peptide-B and Novel Proteins as Potential Regulators of Pulse Pressure in Humans.
Article in Journal of the American Heart Association, 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
backgroundLarge-artery stiffness (LAS) significantly contributes to cardiovascular morbidity and death and is characterized by increased pulse pressure (PP). The biology underlying large-artery stiffness in humans remains incompletely understood. METHODS AND
resultsWe investigated associations between PP and circulating levels of 2941 proteins among 53 016 UK Biobank participants. Analyses were adjusted for age, sex, mean arterial pressure, body mass index and stroke volume. Interaction analyses assessed the effect modification by sex on these relationships. We evaluated causal associations between plasma protein levels and PP, using inverse variance-weighted Mendelian randomization as the main analysis and Bayesian colocalization as a sensitivity analysis. A 5% false discovery rate threshold was used to account for multiple comparisons. Measured levels of 871 proteins were significantly associated with PP when adjusting for age, sex, mean arterial pressure, and body mass index, and 61 remained significantly associated after further adjusting for stroke volume. Top associations included NPPB (natriuretic peptide B), thrombospondin-2, paraoxonase-2, and sclerostin. Genetic analyses indicated that genetically predicted levels for 16 proteins were significantly associated with PP after false discovery rate correction, including fibroblast growth factor 5 (β
conclusionsUsing complementary epidemiological approaches to triangulate findings, our study identifies novel proteins with a putative causal effect on PP. Notably, our findings identify NPPB with high statistical confidence. This may have potentially impactful implications given the current availability of Food and Drug Administration-approved medications to boost NPPB effects.
