  1. aOA IGF-I/GAPDH versus OA IGF-II/GAPDH: p < 0.0003; bp < 0.0001; cp < 0.002. Parametric values are mean ± standard deviation. Non-parametric values are median (quartiles). COL1A, collagen type I alpha chain; GAPDH, glyceraldehyde-3-phosphate dehydrogenase; IGF, insulin-like growth factor; OA, osteoarthritis; TGF-β1, transforming growth factor-β1.
