[1] The Venous Clinical Severity Score (VCSS) was determined by a study staff member blinded to treatment assignment, (i.e., the ‘blinded assessor’). The VCSS rates 9 clinical characteristics of chronic venous disease (pain, varicose veins, venous edema, skin pigmentation, inflammation, induration, and number, duration, and size of ulcers) using Grades 0 to 3 (absent to severe). An additional 0 to 3 points are added for differences in use of compression therapy (compression and elevation) to produce a 30-point maximum flat scale.
[2] Patients were eligible for study if they had a clinical classification of C2–C5 as follows: C2 Varicose veins C3 Edema C4 Skin changes without ulceration C5 Skin changes with healed ulceration
[3] The VVSymQ is a subset of the VEINES-Sym and consists of the 5 symptoms most relevant to patients. The raw score, which can range from 5 to 30, was transformed to a summary VVSymQ score that ranges from 0 (worst possible symptom health) to 100 (best symptom health) using the following formula: VVSymQ: (Transformed Score) = [(Raw Score) – 5] * 4
[4] The VEINES-Sym summary score includes 10 items; 9 venous symptoms (heavy legs, aching legs, swelling, night cramps, heat or burning sensation, restless legs, throbbing, itching, tingling sensation), rated on a 6-point scale of frequency and leg pain rated on a 6-point scale of intensity (very severe, severe, moderate, mild, very mild, none). It can range from 0 to 100, with a ‘0’ score indicating all symptoms were present all of the time in the past week and a ‘100’ score indicating none of the symptoms were present at any time in the previous week.
