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

backgroundGiven an epidemiological association between hypertension and osteoarthritis, we aim to elucidate how vascular pathology triggers avascular articular cartilage loss by comparing vascular and joint phenotypes between spontaneously hypertensive rats and normotensive Wistar Kyoto rats at tissue, cellular, and molecular levels.

methodsSystemic and local endothelial function were assessed via blood pressure monitoring and photoacoustic imaging of knee joints, respectively (n=5-6). Tissue and cellular damages in articular cartilage, subchondral bone, and synovium were systemically evaluated by radiological and histological examination (n=6). Endothelial transcriptional changes were delineated via bulk RNA-seq (n=3). The secretome of human endothelial cells under oxidative stress was analyzed via proteomics to identify key factors in chondrocyte senescence (n=4). Captopril, an antihypertensive medication, was adopted as a tool to rescue chondrocyte senescence and osteoarthritis both in vitro (n=3) and in vivo (n=6).

resultsCompared with Wistar Kyoto rats, spontaneously hypertensive rats exhibited higher blood pressure and local joint hypoxia with increased endothelial oxidative stress as early as 3 months old. Notably, these endothelial dysfunctions preceded the onset of structural joint damage. By 9 months of age, spontaneously hypertensive rats developed osteoarthritis-like pathology characterized by senescent chondrocyte accumulation and cartilage degradation, which could be mitigated by captopril. Transcriptomic and proteomic analyses of rat and human endothelial cells revealed upregulated IGFBPs (insulin-like growth factor-binding proteins). Among them, IGFBP6 was identified to induce chondrocyte senescence in vitro. This effect can be modified by captopril treatment.

conclusionsSystemic vascular dysfunction may induce local joint damage with upregulation of endothelial IGFBPs secretion such as IGFBP6. This study highlights a potential therapeutic target for preventing joint structural damage by addressing endothelial dysfunction.
