What researchers measure

Primary outcomes

  1. Global improvement on a five point scale

    The degree of improvement was evaluated according to change of severity of each symptom at the time of enrollment (baseline) and in Week 12 after initiation of dosing (or at discontinuation)

    Time frame: week 12

  2. Number of patients with adverse drug reactions

    Time frame: up to week 12

Secondary outcomes

  1. Improvement per symptom on a five point scale

    Time frame: 12 weeks

  2. Change in circumference measurements of calf in centimetres

    Time frame: baseline, 12 weeks

  3. Change in circumference measurements of ankle in centimetres

    Time frame: baseline, 12 weeks

  4. Subject's impression on improvement on a five point scale
