X-ray measurement of the evolution of the knee articular interline at 6 and 12 months after the administration of treatments

Time	Control	BM-MSCs
		Low-dose	High-dose
6 months	−3 (−6, 0)	0 (−1, 0)	0 (−1, 1)
12 months	−4 (−18, 0)	0 (0, 3)	0 (−1, 2)

For each group of treatment, variation for knee joint space width, which was measured in mm, was calculated by subtracting, for each patient of the group, the value at 6 or 12 months from the baseline value. Data are presented as the median (IQR) of each group
