Abstract
PURPOSE: To estimate gains in health utility for two different catheter features and a support service related to urinary catheters used for intermittent catheterization. PATIENTS AND METHODS: Two internet-based time trade-off (TTO) surveys were undertaken to value vignettes describing two innovative catheter features and a support service. The first TTO survey "Size and Service" included catheters with compact design and the availability of a support service for users; the second TTO survey "Phthalates" included avoidance of potentially harmful phthalates in the material of the catheters. All participants were from the UK; they traded health states against a time horizon that matched their total life expectancy. Sensitivity analyses were done to estimate the impact of extreme values on disutilities. RESULTS: The participants (n=890) estimated the incremental value of 0.031 (95% CI: 0.024-0.039), 0.009 (95% CI: 0.003-0.015), and 0.037 (95% CI: 0.027-0.046), respectively, for catheters with compact design, availability of support service, and catheters not containing phthalates. CONCLUSIONS: Participants valued all three improvements in catheter design. To capture the impact of such design improvements on quality of life and utilities, vignette-based approaches can be a useful supplement to the conventional, generic tools.

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
