Figure 4

Treatment satisfaction was higher in the PPT5α group than in the placebo group at a 3-month visit. The level of patient’s satisfaction with the treatment (a) and the time to positive response (visit in which an improvement is observed) (b) were self-assessed by a questionnaire and scored on a 4-point scale (0 = not at all, 4 = very satisfied, 0 = no improvement, and 4 = much improvement, respectively). Results were expressed by means of Box–Whisker plots depicting medians, first and third quartiles, and minimum and maximum values. A value < 0.05 was considered statistically significant.
