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
During aging, peripheral nerves undergo structural and cellular changes that trigger loss of function, impair quality of life, and increase disease risk. During peripheral nerve aging there are cellular and molecular changes, such as increased extracellular matrix deposition. The mechanisms behind these aging-induced alterations remain unclear. Here, we profile mouse sciatic nerves using single nucleus transcriptomics and unravel changes in macrophage subtypes during nerve aging. Phagocytic macrophage numbers increase at the onset of aging, followed by higher numbers of chronic inflammatory macrophages. Based on ligand-receptor analysis, we predict that increased fibroblast growth factor (FGF) signaling from adipocytes activates a chondrocyte-like neural fibroblast state during peripheral nerve aging. Finally, we show that FGF2 induces the co-expression of the chondrocyte markers SOX9 and FOXC2 in senescent human perineurial fibroblast, that can be blocked with FGF1. In conclusion, our findings reveal some of the molecular mechanisms of peripheral nerve aging by FGF-regulated induction of a chondrocyte-like fibroblast state.
