Outcome Measures
Primary Outcome Measures
- Effective rate [From randomization of the first subject until the last subject complete 6 months treatment]
Effective rate = (cure + obvious effect + effective)/total cases *100%;
Secondary Outcome Measures
- SALT score change [From randomization of the first subject until the last subject complete 6 months treatment]
Score and take photos (4 areas on the head), taking photos in the same position and light condition each time;
- Quality of Life (AASIS) [From randomization of the first subject until the last subject complete 6 months treatment]
AASIS was used to score the quality of life of the subjects
Other Outcome Measures
- Safety variables will be summarized using descriptive statistics based on adverse events collection [From randomization of the first subject until the last subject complete 6 months treatment]
Patients with adverse events/all patients *100%
