Vascular adventitial cells and vascular remodeling: when a harp of thousand strings does not keep in tune so long.
Review in Frontiers in physiology, 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
The tunica adventitia of blood vessels is a highly heterogeneous microenvironment comprising diverse cell types. Beyond providing structural scaffolding, adventitial fibroblasts act as dynamic, responsive cells that contribute to vascular homeostasis mainly through regulation of collagen, fibronectin and elastin expression and paracrine effects that promote vascular inflammation. Their dysregulation leads to the onset and progression of several diseases. Signaling pathways in adventitial fibroblasts, particularly DDR2, hypoxia-ERK1/2 MAPK and PI3K/Akt signaling, impact cell proliferation, pro-fibrotic gene expression and cellular response to stress. Furthermore, non-coding RNAs and novel epigenetic mechanisms significantly impact adventitial fibroblast function. Adventitial fibroblasts promote sex-related variations in the prevalence and severity of vascular diseases. Rapid advances in single-cell transcriptomics, biomarker development and other molecular and imaging techniques promise deeper insights into adventitial fibroblast biology, unravelling their heterogeneity and functional variability, and their role in extracellular matrix remodeling and paracrine signaling. These in turn would pave the way for innovative strategies to target pro-fibrotic fibroblast subpopulations and prevent adverse vascular remodeling. This review provides an overview of adventitial fibroblast function and the role of these cells in atherosclerosis, hypertension, diabetes, aneurysm and age-related vascular dysfunction, underscoring the need for a paradigm shift in vascular biology, positioning the adventitia as a critical regulator of vascular health and disease.
