Diagnostic characteristic of ADC for differentiating treatment response. The cutoff value was selected to maximize the sum of sensitivity and specificity. The numbers in the parentheses are the lower and upper limits of 95% confidence interval.

Parameter	Cutoff value	Sensitivity (%)	Specificity (%)	AUC*
Pre-Tx	1.11×10−3 mm2/s	65 (44, 82)	86 (42, 99)	0.80 (0.62, 0.99)
Wk1-Tx/Pre-Tx	1.11	86 (64, 96)	83 (36, 99)	0.88 (0.74, 1.00)
Post-Tx/Pre-Tx	1.11	82 (56, 95)	80 (30, 99)	0.80 (0.57, 1.00)
