Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of patients with non-serious and serious adverse events | Change from baseline up to week 12 after injection. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Wrinkle Severity Rating Scale (WSRS) Evaluation | Change from baseline at week 2, 6 and 12. | An improvement was judged by the outcome of the preoperative grade minus the postoperative grade in accordance with the Wrinkle Severity Rating Scale (WSRS).The severity was measured using the Wrinkle Severity Rating Scale (WSRS), where 0 = Absent, 1 = Mild, 2 = Moderate, 3 = Severe, and 4 = Extreme, which is an ordinal scale. |
| Global Aesthetic Improvement Scale (GAIS) Evaluation | Change from baseline at week 2, 6 and 12. | An improvement was judged by the outcome of the preoperative grade minus the postoperative grade in accordance with the Global Aesthetic Improvement Scale (GAIS). |
