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

backgroundOsteoarthritis (OA) is a prevalent degenerative joint disease characterized by cartilage destruction and synovial inflammation, with macrophage-mediated immune dysregulation playing a pivotal role. Photobiomodulation (PBM), a non-invasive light therapy, has shown promise in alleviating OA by modulating macrophage polarization. However, the precise underlying molecular mechanisms remain unclear.

methodsWe integrated single-cell and bulk RNA sequencing data from the Gene Expression Omnibus (GEO) database to identify key cellular players and pathways in OA. The functional effects of PBM were assessed in vitro using ATDC5 chondrogenic cell and macrophage co-cultures, and in vivo using the DMM-induced OA murine model with macrophage depletion and PBM intervention.

resultsAnalysis of single-cell and bulk RNA sequencing data revealed a strong correlation between macrophage and OA, highlighting the importance of the IL-6/JAK/STAT signalling pathway in the regulation of synovial macrophage and OA progression. In vitro experiments demonstrated that PBM intervention enhanced chondrocyte proliferation while suppressing catabolic activity and inhibiting macrophage polarization towards a pro-inflammatory phenotype through the IL-6/JAK/STAT pathway. In vivo experiments further confirmed that PBM intervention attenuated articular cartilage degradation and synovial hyperplasia via IL-6/JAK/STAT-dependent modulation of macrophage polarization.

conclusionsOur study demonstrated that PBM intervention mitigated OA progression by regulating macrophage polarization through the IL-6/JAK/STAT pathway, emphasizing the therapeutic potential of immune modulation in OA management. These findings provide a mechanistic basis for PBM intervention as a nonpharmacological strategy for joint degeneration.
