Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | itching scores | 1 years | The patients rate the itching on a visual analogue scale (VAS) before and after the treatment. A VAS is a 100-mm long horizontal line with verbal descriptors at each end to express the extremes of the itching feeling. The most severe itching equals to score 10, and no itching equals to score 0. Patients marked the point on the line that best corresponded to their itching severity. |
| Secondary | percentage of hypopigmented skin | 1 years | Doctors rate the hypopigmented skin on a vulva surface area scale (VSAS) before and after treatment through colposcopy. The vulva area is divided into six regions as labia majora, labia minora, interlabial sulci, clitoris and clitoral hood, perineum, and perianal area. The investigators estimated that the area percentage of labia majora, labia minora, interlabial sulci, clitoris and clitoral hood, perineum, and perianal area was 48%, 24%, 4%, 4%, 10% and 10% differently. Among the six regions, interlabial sulci, clitoris and clitoral hood, perineum, and perianal area could be divided into four equal proportions at most when the area percentage was calculated. And each side of labia majora and labia minora could be divided into four equal proportions at most. If all the vulva area is involved, the VSAS score is 100%, and if no area of vulva is involed, the VSAS score is 0%. |
