[2] Participants were classified based on the severity as mild (Category A), moderate (Category B), and severe (Category C).
[3] SDM: 20 items questionnaire, each item rated from 0 to 4, 0=complete absence of symptom and 4=very bothersome symptom. Overall score: sum of scores for each of 20 items of questionnaire, with 0=best health and 80=worst health. A positive change from baseline indicates decline in participant’s quality of life. Number of participants evaluable=55.
