SEM = SD of the measure multiplied by the square root of 1 minus its reliability coefficient ICC from the test-retest assessment. ICC1: evaluated among stable subjects (BPI-DN item 5 < 20%) between week 8 and week 12. ICC2: evaluated among stable subjects (EQ-5D VAS change < 20%) between week 8 and week 12.
