1 · What the graph read from it

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.

2 · The registry

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

Liver fibrosis remains a significant clinical challenge with limited therapeutic options. Apoptotic extracellular vesicles (apoVs) derived from macrophages have emerged as promising mediators of tissue repair, but their role in shaping liver fibrosis is poorly understood. Here, we demonstrate that M2 macrophage-derived apoVs (M2-apoVs) alleviate liver fibrosis by modulating hepatic stellate cells (HSCs) activation. Mechanistically, M2-apoVs deliver miR-1224-5p to HSCs, which suppresses the SP1/TGF-β pathway, thereby inhibiting fibrogenic gene expression, proliferation, and migration. In vitro, M2-apoVs reduced extracellular matrix (ECM) deposition by downregulating the expression of collagen I (Col I) and α-smooth muscle actin (α-SMA) in HSCs. Furthermore, M2-apoVs promoted the establishment of an antifibrotic microenvironment by regulating macrophage polarization and HSC-macrophage crosstalk. In a CCl₄-induced liver fibrosis mouse model, M2-apoVs treatment significantly reduced collagen accumulation and improved liver histology. Our findings revealed a novel miR-1224-5p/SP1/TGF-β regulatory axis in liver fibrosis and highlighted the therapeutic potential of M2-apoVs as a cell-free strategy for treating fibrotic liver diseases.
