WORMS score before administration of treatments and 6 and 12 months afterwards

Time	Control	BM-MSCs
		Low-dose	High-dose
Baseline	79 (41, 94)	75 (64, 107)	60 (53, 84)
6 months	78 (34, 107)	70 (57, 126)	53 (51, 90)
12 months	83 (25, 95)	90 (67, 140)	53 (46, 82)
12 months evolution	−0.5 (−16, 15)	2.5 (−3, 25)	−4 (−22, 2)

The overall WORMS scores at baseline and 6 and 12 months afterwards are presented as the median (IQR) of each group. The evolution within each treatment group at 12 months is also presented, and was calculated by subtracting for each patient the values at 12 months from the corresponding baseline values. Data are the median (IQR) of each group
