The general approach of the statistical methodology is the following:

• The qualitative variables are described with number and percent of each level.
• The quantitative variables are described with mean and standard deviation.
• All statistical hypotheses are performed at the 5% significance level using 2-sided tests.
• Given the large sample size, no normality assessment will be done.
• Mean reduction rate for quantitative variables is calculated as (mean v0 - mean v1)/mean v0)*100.
• Due to the high number of zeros at inclusion in the self-assessment quantitative criteria, analyses will concern only patient with an intensity above 0 at inclusion or at final visit.
• Response rate for qualitative variables is calculated as the percent of patients with at least on level decrease between the two visits.
• Response rate for satisfaction is the percent of patients declaring being Satisfied or Very satisfied.
• Response rate for tolerance is the percent of patients declaring the tolerance High or Excellent.
