结局指标
主要结局
Percentage of Participants With a Reduction in Chest Wrinkles at 90 Days Post Treatment
时间窗: 90 Days post-treatment
Assessment of improvement, in a blinded fashion, using a Chest Wrinkle Scale at 90 days post-treatment. However, during conduct of the trial, the Chest Wrinkle scale was deemed inadequate as a primary endpoint in this study. Therefore, conduct of a traditional blinded masked assessment, the gold-standard measure in aesthetics, was used as the primary endpoint,i.e., improvement in wrinkles and lines of the décolletage as determined by a blinded, masked, qualitative assessment of photographs at 90 days post-treatment compared to baseline. "Improvement" = a blinded evaluator assessed an "Improvement" when evaluating a masked, paired photo set and correctly chose the Post treatment photo. "Incorrect" = a blinded evaluator assessed an "Improvement" when evaluating a masked, paired photo set but incorrectly chose the Post treatment photo.
