subjects achieving at least 1-grade improvement from baseline using the Galderma Chin Retrusion Scale (GCRS; 0=no retrusion, 1=mild retrusion, 2=moderate retrusion, 3=substantial retrusion) as assessed by blinded evaluator

Summary of change from Baseline to Week 12 in the FACE-Q Satisfaction with Chin, where subjects were asked about their satisfaction with treatment outcome on their chin. Higher scores reflect a better outcome. Scale consists of 10 questions and subjects select level of satisfaction for each question from/to Very dissatisfied = 1, Somewhat dissatisfied = 2, Somewhat satisfied = 3, Very satisfied = 4. A Conversion Table converts raw scale summed score into a score from 0 (worst) to 100 (best). If missing data is less than 50% of the scale's items, the mean of the completed items is used (Rasch Transformed Total Score: BOCF (ITT Population).

ITT Population; NOTE: Of the 140 subjects enrolled, 1 subject was randomized but did not complete baseline FACE-Q before withdrawing consent and is, therefore, not included in this table.

Response rates, defined by at least 1 point improvement from baseline using the Galderma Chin Retrusion Scale (GCRS), as assessed by the Blinded Evaluator, at 24,36, and 48 weeks after the last injection for the treatment group or after baseline if randomized to no treatment

ITT population

Aesthetic improvement (overall appearance) after treatment with Restylane® Defyne compared to no-treatment control, as determined by assessments using the Global Aesthetic Improvement Scale (GAIS). Assessments were performed at 12, 24, 36, and 48 weeks after treatment. Treating Investigators and subjects separately rated aesthetic improvement of the chin from baseline appearance, where a higher score reflects reporting of greater improvement. The subjects and Investigators select a score from the following categorical scale: Very much improved = 3; Much improved = 2; Improved = 1; No change = 0; Worse = -1; Much worse = -2; Very much worse = -3. Scores range from -3 (worst) to 3 (best). Higher scores reflect a better outcome. The Responder Rate is defined as the number and percent of subjects with a rating of at least "Improved" based off of subject's/investigator's (as appropriate) assessment of the GAIS.

Summary of Total Volume Change in the Chin Area Measured by Digital 3D Photography at Each Visit (ITT Population). Total volume change corresponds to net volume change from baseline in the chin area.
