Lymphatic vascular aging and age-related bone loss: current status and future perspectives.
Review in Frontiers in immunology, 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
Age-related bone loss is a major contributor to osteoporosis and fragility fractures in older adults. Skeletal aging is accompanied by reduced bone mineral density, impaired bone microarchitecture, chronic low-grade inflammation, and immune dysregulation. Lymphatic vascular aging refers to age-related structural and functional decline of lymphatic vessels. This decline impairs immune surveillance and inflammatory mediator clearance, thereby disrupting tissue homeostasis. Age-related lymphatic dysfunction impairs drainage and inflammatory clearance. This allows inflammatory mediators, including IL-6 and TNF-α, to persist in bone-associated tissues, thereby promoting osteoclastogenesis and resorption-dominant remodeling. Age-related lymphatic dysfunction also affects VEGF-C/VEGFR-3 signaling, chemokine-mediated immune trafficking, and marrow niche support. These changes link drainage failure to osteoimmune imbalance and delayed bone repair. Current evidence supports a link between lymphatic vascular dysfunction and skeletal degeneration. Most evidence comes from animal models, bone injury studies, or diseases with secondary lymphatic defects, whereas direct clinical evidence in human age-related osteoporosis remains limited. This review summarizes current evidence linking lymphatic dysfunction to skeletal degeneration, examines the context-dependent roles of lymphatic remodeling in skeletal homeostasis, and discusses emerging therapeutic strategies targeting the lymphatic-bone axis. Future studies should define clinically relevant lymphatic alterations and determine whether restoring lymphatic homeostasis can mitigate age-related bone loss.
