Abstract
OBJECTIVE: The authors set out to quantify the health state utility assessment of living with the physical appearance of the aging neck following massive weight loss. Described utility scores may help to establish the health burden of the aging neck in the growing bariatric patient population. STUDY DESIGN: Prospective cohort observational study. SETTING: Tertiary referral medical center. SUBJECTS AND METHODS: Three validated tools were used to determine utility scores for living with an aging neck: visual analog scale (VAS), time trade-off (TTO), and standard gamble (SG). A 5-point Likert scale was used to evaluate the subjects' ease of understanding. A prospective sample of volunteers from the general population and medical students was used for this assessment. RESULTS: In total, 118 prospective volunteers were included in the survey. All measures (VAS, TTO, SG); (0.89 ± 0.07, 0.94 ± 0.08, and 0.95 ± 0.10, respectively) varied (P < .0001) from the corresponding ones for monocular blindness (0.62 ± 0.18, 0.87 ± 0.15, and 0.85 ± 0.20, respectively) and binocular blindness (0.32 ± 0.18, 0.66 ± 0.25, and 0.64 ± 0.28, respectively). CONCLUSION: The authors objectified the health state of living with an aging neck in the massive weight loss patient with utility scores (TTO, 0.94) comparable with those living with obstructive sleep apnea. This sample population, if faced with an aging neck following massive weight loss, would undertake a neck rejuvenation procedure with a theoretical 5% chance of mortality and would be willing to trade 2.1 years of remaining life-years to attain this procedure.

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
