Abstract
BACKGROUND: Use of botulinum toxin for esthetic purposes has rapidly expanded over the last 20 years. IncobotulinumtoxinA, also known as NT 201, is a new botulinum toxin type A (150 kDa) that is free from complexing proteins. OBJECTIVES: A prospective, multicenter, randomized, rater- and patient-blind, international Phase III trial to investigate the noninferiority of incobotulinumtoxinA to another botulinum toxin type A, onabotulinumtoxinA, in the treatment of glabellar frown lines. METHODS: A total of 381 patients were randomized in a 3:1 (incobotulinumtoxinA:onabotulinumtoxinA) ratio to receive 24 U incobotulinumtoxinA of or onabotulinumtoxinA. Efficacy end points included the percentage of responders (patients with an improvement of ≥1 point on a 4-point facial wrinkle scale) at maximum frown at weeks 4 and 12 as assessed by the investigators, and a panel of independent raters based on standardized digital photographs. RESULTS: Four weeks after injection, response rates at maximum frown were 96.4% in the incobotulinumtoxinA group and 95.7% in the onabotulinumtoxinA group as assessed by independent raters. Analysis of the data confirmed the noninferiority of incobotulinumtoxinA. Response rates at rest were lower for both products. The rate of adverse events was low. CONCLUSION: IncobotulinumtoxinA is equally as effective as onabotulinumtoxinA in the treatment of glabellar frown lines. Both preparations were well tolerated.

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
