Differences of absolute values over 6 months for ADC, conspicuity and signal intensity for each of the two arms included in the study

	Placebo	Dutasteride	p
ADC lesion	- 0.03 (±0.13)	0.08 (±0.17)	0.033
Conspicuity	0.11 (±0.33)	- 0.16 (±0.28)	0.012
ADC TZ	- 0.07 (±0.16)	0.04 (±0.16)	0.039
ADC PZ	0.05 (±0.29)	- 0.07 (±0.19)	0.132
SI lesion	3.75 (±11.38)	- 5.93 (±15.42)	0.036

Note - Data are means with standard deviations in parentheses. MRI: magnetic resonance imaging; ADC: apparent diffusion coefficient (x 10^-3 mm²/s); TZ: transition zone; PZ: peripheral zone; SI: signal intensity. Unpaired t test used for comparison between placebo and dutasteride groups
