Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in the Blinded Evaluators' Live Assessment Using the Galderma Chin Retrusion Scale (GCRS) at Month 3 | Baseline (last non-missing observation prior to the first administration of study product) and Month 3 | GCRS is a validated 4-grade scale to assess the chin retrusion from no retrusion (0) to severe retrusion (3) which was described as follows; "0- No retrusion", "1- Mild retrusion", "2- Moderate retrusion", "3- Severe retrusion". Higher scores indicated more severity. Least squares (LS) mean, and 95 percent (%) confidence interval (CI) were obtained from a general linear mixed random intercept model with treatment group and baseline Galderma Chin Retrusion Scale score as fixed factors. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Responder Rate Based on the Blinded Evaluator's Live Assessment Using the GCRS at Months 6, 9, and 12 | At Months 6, 9, and 12 | GCRS is a validated 4-grade scale to assess the chin retrusion from no retrusion (0) to severe retrusion (3) which was described as follows; "0- No retrusion", "1- Mild retrusion", "2- Moderate retrusion", "3- Severe retrusion". Higher scores indicated more severity. Responder rate was defined as percentage of participants with an improvement of at least one grade on the GCRS from baseline. 95% CI was calculated using Clopper-Pearson method. |
