Abstract
BACKGROUND OnabotulinumtoxinA is an established treatment for glabellar frown lines, but its effects on lines at repose are less well documented. OBJECTIVE To assess the effect of onabotulinumtoxinA on elimination of mild lines at repose. METHODS Data from two randomized, double-blind, placebo-controlled studies were included. Elimination of mild lines at repose was defined as change from mild to none on the Facial Wrinkle Scale. RESULTS Analysis included 183 participants who received 20 U of onabotulinumtoxinA and 64 participants who received placebo, all with mild lines at repose at baseline. Participants were evaluated 7, 30, 60, 90, and 120 days posttreatment. Compared to placebo, onabotulinumtoxinA-treated participants were significantly more likely to have their lines at repose eliminated at each study day; [odds ratios ranged from 42.7 (95% confidence interval (CI)=12.9–141.9) at day 30 to 4.9 (95% CI=2.2–10.8) at day 120 (p<.0001 at each day)]. The highest response rate was observed at day 30 (68%). CONCLUSION OnabotulinumtoxinA has demonstrated the ability to eliminate mild glabellar lines at repose for a significant number of patients. This effect, albeit more subtle than the effect on dynamic or more severe glabellar lines, may be an important treatment goal for patients who seek a smoother appearance at repose. Drs. A.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
