Table 2. Permeability Parameters with Significant Differences between the EP and NEP Groups.

Permeability Parameter	PFS Group	Median	IQR	P*
Ktrans 95th PV	NEP	0.0258	0.0325	0.015
	EP	0.0484	0.0414
Mean Ktrans	NEP	0.0120	0.0117	0.026
	EP	0.0165	0.0350
Median Ve	NEP	1.30	1.35	0.042
	EP	2.00	2.50

^*Calculated with the Mann-Whitney U test. EP = early progression, IQR = interquartile ranges, NEP = nonearly progression, PFS = progression-free survival, PV = percentile value
