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

Rotator cuff tears are common musculotendinous injuries with a high risk of permanent functional disability. Following surgical repair, sub-optimal patient outcomes are directly correlated with poor muscle quality; namely, injury site fatty infiltration, fibrosis, and muscle atrophy. Muscle resident fibro-adipogenic progenitor cells (FAPs) have been identified as key regulators of post-injury skeletal muscle regeneration and repair by maintaining a pro-myogenic environment. In this work, human FAPs (hFAPs) were encapsulated into hyaluronic acid (HyA)-based hydrogels functionalized with bsp-RGD(15) cell adhesion peptide, heparin, and a matrix metalloproteinase (MMP)-cleavable crosslinker. Hydrogel-encapsulated hFAPs increased expression of the pro-myogenic marker UCP1 and production of the anti-inflammatory cytokine IL-10 while downregulating the expression of the fibrotic marker αSMA over time. A murine model of unilateral rotator cuff transection, denervation, and delayed repair was treated with the HyA hydrogel or PBS and compared to a contralateral, non-injured control limb. Muscle histology 6 weeks post-repair revealed that the hydrogel reduced fibrosis, FI, and muscle atrophy while supporting vascularization of the injured tissue region. Collectively, these results suggest that the HyA hydrogel alone can promote muscle regeneration in a clinically relevant delayed repair model of rotator cuff tear, which is hypothesized due to controlled FAP differentiation into pro-myogenic lineages.
