Correlation with VAS-change	r(R2)	p-value
pre-MPP	-0.447 (0.20)	0.063
post-MPP	-0.21 (0.04)	0.402
MPP-change	0.60 (0.36)	0.009

post-PTI	-0.093 (0.008)	0.714
PTI-change	0.77 (0.59)	<0.001
DS of MPP	0.01 (<0.001)	0.969

pre, pre-treatment; post, post-treatment; change, post-treatment value – pre-treatment value; DS, distance of shifting.
