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

Peripheral nerve injuries, particularly those affecting the sciatic nerve, often result in incomplete functional recovery due to the limited regenerative capacity of adult peripheral nerves. To elucidate the cellular and molecular mechanisms underlying nerve regeneration, we performed single-cell RNA sequencing (scRNA-seq) on rat sciatic nerve tissues at seven time points (Days 0, 1, 3, 5, 7, 10, and 14) following transection injury. Through unsupervised clustering, we identified four major cellular compartments-neurofibroblasts (NFs), glial cells (Glis), immune cells, and vascular cells-and delineated their dynamic trajectories during regeneration. Early responses were dominated by macrophage (Mac) and granulocyte infiltration (Day 1), followed by proliferative expansion of proliferating mesenchymal fibroblasts (NF5) and repair Schwann cells (Gli0) by Days 3-5. Vascular remodeling commenced from Day 7, while Glis progressively transitioned to mature myelinating states (Gli2/Gli5) by Day 14. Pseudotime analysis revealed subtype-specific reprogramming in both Macs and Glis, and cell-cell communication analysis uncovered key ligand-receptor interactions-particularly collagen and PTN signaling between Macs, NFs, and Glis. Bulk transcriptomic validation confirmed sustained and spatially distinct activation of the TGF-[Formula: see text] signaling pathway across cell types and anatomical locations. Comparative analysis with a sciatic nerve crush injury model revealed a stronger early immune response and delayed Gli recovery in transection injury, indicating a narrowed therapeutic window. Together, this work provides a time-resolved single-cell atlas of peripheral nerve regeneration, defines key regulatory circuits within the immune-NF-Gli axis, and identifies phase-specific therapeutic targets-such as early Mac heterogeneity, NF4-mediated matrix remodeling, and Schwann cell remyelination-for enhancing functional recovery following severe nerve injury.
