Abstract

fetched live from OpenAlex

BACKGROUND: A validated scale is needed for objective and reproducible comparisons of temple appearance before and after aesthetic treatment in practice and clinical studies. OBJECTIVE: To describe the development and validation of the 5-point photonumeric Allergan Temple Hollowing Scale. METHODS: The scale was developed to include an assessment guide, verbal descriptors, morphed images, and real subject images for each grade. The clinical significance of a 1-point score difference was evaluated in a review of image pairs representing varying differences in severity. Interrater and intrarater reliability was evaluated in a live-subject validation study (N = 298) completed during 2 sessions occurring 3 weeks apart. RESULTS: A score difference of ≥1 point was shown to reflect a clinically significant difference (mean [95% confidence interval] absolute score difference, 1.1 [0.94-1.26] for clinically different image pairs and 0.67 [0.51-0.83] for not clinically different pairs). Intrarater agreement between the 2 validation sessions was almost perfect (mean weighted kappa = 0.86). Interrater agreement was almost perfect during the second session (0.81, primary endpoint). CONCLUSION: The Allergan Temple Hollowing Scale is a validated and reliable scale for physician rating of temple volume deficit.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
