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
backgroundOsteoarthritis (OA) is a joint disorder that severely affects patients' mobility, overall health, and ability to perform daily activities. Despite advancements in therapeutic strategies, stem cell-based therapies for OA still face challenges, particularly in enhancing the antioxidative capacity of stem cells to improve therapeutic outcomes. Therefore, this study aimed to explore the potential of β-sitosterol in this context.
methodsThis study evaluated the protective effects of β-sitosterol on bone marrow-derived mesenchymal stem cells (BMSCs) and chondrocytes under oxidative stress conditions and assessed its potential in promoting cartilage repair in a rabbit OA model. Cell viability, gene expression, oxidative stress markers, and mitochondrial function were examined. In vivo therapeutic effects were evaluated through histological and immunohistochemical analyses.
resultsThe results revealed that β-sitosterol significantly enhanced BMSC viability, upregulated the expression of Col2a1 and aggrecan, while inhibiting MMP13 expression. Furthermore, β-sitosterol effectively alleviated oxidative stress and preserved mitochondrial function in BMSCs. Notably, BMSCs pretreated with β-Sitosterol exhibited a higher potential for facilitating cartilage regeneration in the OA model, as evidence by histopathological analysis.
conclusionsThese findings suggest that β-sitosterol possesses significant antioxidative and chondroprotective properties, which enhance the therapeutic efficacy of BMSCs in addressing OA-related cartilage damage.
