A Novel Lymphosome-Based Long-Lasting Rat Tail Model of Lymphedema.

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: Secondary extremity lymphedema is a chronic and progressive condition caused by obstructed lymphatic drainage, commonly following lymphadenectomy, infection, or trauma. Rodent models are preferred for experimental lymphedema research due to cost-effectiveness and reproducibility. Currently, rat tail models encounter limitations due to transient swelling and their inability to fully replicate the comprehensive pathophysiology of lymphedema, particularly concerning the effects of lymph node removal. Methods: We developed a series of rat tail lymphedema models incorporating skin resection, deep lymphatic vessel disruption, and gluteal lymph node (GLN) excision to assess effects on lymphatic architecture, inflammation, and fibrosis. Indocyanine green (ICG) lymphography was used to visualize lymphatic function. Tail volume and circumference were measured weekly, and histological assessments quantified fibrosis and fibroadipose thickening. Bulk RNA sequencing was performed to characterize the inflammatory processes triggered by GLN removal. Results: The combined model (skin removal, deep lymphatic disruption, and GLN excision) resulted in severe and persistent lymphedema marked by progressive swelling and pronounced fibrosis. ICG lymphography confirmed disruption of superficial lymphatic flow with partial recanalization of deep channels. Notably, lymphangiogenesis was observed at the GLN excision site, forming compensatory pathways connecting the tail to the popliteal lymph nodes. Histology revealed extensive collagen deposition and fibroadipose thickening in groups with lymph node removal, with the combined model showing the most pronounced changes. Bulk RNA-sequencing confirmed the removal of GLN involving the inflammatory and fibrosis process in the tail model. Conclusion: This lymphosome-based rat tail model successfully replicates key features of lymphedema, including sustained swelling, lymphatic disruption, inflammation, and fibrosis.
