The Role of Phagocytic Cells in the Achilles Tendon.
Review in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Macrophages and other phagocytic cells are central regulators of tendon immunobiology, orchestrating inflammation, tissue repair, and extracellular matrix (ECM) remodeling in the tendons. They derive from circulating monocytes and resident tendon-specific populations, including tenophages. Macrophage polarization along the M1/M2 axis exerts a decisive influence on tendon healing trajectories. Activated M1 macrophages promote the early healing phase for debris clearance initiating the reparative cascade. However, their sustained activity leads to inflammation, ECM degradation, impaired healing, tendinopathy, and heterotopic ossification (HO). Conversely, a timed shift toward activated M2 macrophages promotes resolution of inflammation, angiogenesis, ECM deposition, and fibrocartilage formation, whereas excessive or prolonged M2 activity facilitates adhesion formation, fibrosis, scarring and HO. Recent single-cell and spatial profiling studies showed macrophage heterogeneity across tendon compartments, thereby extending the classical M1/M2 paradigm and underscoring the relevance of macrophages/resident tendon cell's interaction in tendon-specific local niches. Mechanobiological stimuli (depending on magnitude, frequency and duration) further modulate macrophage phenotypes and tendon healing. Emerging coculture models and human tendon-on-chip systems provide high-resolution platforms for dissecting these spatiotemporal interactions. Promising therapeutic approaches comprise the application of extracellular vesicles, controlled mechanoloading regimens, and immunomodulatory biomaterials demonstrating potential to induce regenerative macrophage signatures for improved healing outcomes. Notably, platelet-rich plasma (PRP) formulations shape macrophage responses: leukocyte-rich PRP preferentially promotes M1 activity whereas leukocyte-poor PRP supports M2 polarization. Thus, mechano- and immunomodulatory strategies can offer precise control over macrophage dynamics. Regarding the Achilles tendon pathologies, such approaches are helpful by directing macrophage-mediated inflammation towards effective tendon healing outcomes.
