Coefficient of variation mean ± SD for genes that were upregulated or downregulated relative to other treatments, or not differentially expressed (Non-DEG).

To focus on differences among OA and ambient treatments, the 16 genes that were only differentially expressed among moderate and severe OA were not included in these calculations.

为聚焦骨关节炎（Osteoarthritis, OA）与环境处理组间的差异，本次计算分析未纳入仅在中度与重度骨关节炎中呈现差异表达的16个基因。
