Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Leg discomfort (including tired and heavy legs) measured using visual analogue score (VAS) at each visit (baseline, day 14, day 28, day 56) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Appearence of telangiectsasia assessed by a dermatologist using an arbitrary scale where 0 indicates absence, 1 very mild, 2 mild, 3 moderate, and 4 severe. This is assessed at each visit (baseline, day 14, day 28, day 56) 2. Blood flow rate is measured using a laser doppler (PeriFlux 6000, Perimed Italia Srl, Cuggiono, Milan, Italy) at each visit (baseline, day 14, day 28, day 56) 3. Skin color, which is related to the hemoglobin content in the superficial microvessels, is measured using a colorimeter (Mexameter® MX18, Courage + Khazaka electronic GmbH, Köln, Germany) at each visit (baseline, day 14, day 28, day 56) 4. Quality of life is assessed using the CIVQ20 questionnaire at baseline and at the end of the study (day 56) 5. The perceived efficacy (as perceived by each participant) is assessed using a 5-point scale (strongly disagree or not satisfied at all, disagree or not satisfied, neither disagree nor agree or neither dissatisfied nor satisfied, agree or satisfied, completely agree or very satisfied) at baseline and at the end of the study (day 56) | — |
