Abstract
The aim was to assess whether subject's participation in early-phase chemoprevention trials was satisfactory and identify features associated with subjects' satisfaction. Thirteen trials that investigated a range of candidate agents from 2006 to 2021 by the Cancer Prevention Network were included. The five-item "Was It Worth It?" (WIWI) questionnaire was administered to all subjects at the end of each trial's intervention or at early termination. Satisfied overall was defined as a participant response of "yes" to the first three questions. Six hundred ninety-one participants from the United States, Canada, Puerto Rico, and Honduras enrolled on a trial. Six hundred fifty-two (94.4%) completed the WIWI questionnaire. Of these, 493 (75.6%) were White, non-Hispanic/Latino; 39 (6.0%) Black, non-Hispanic/Latino; 98 (15.0%) Hispanic/Latino; and 8 (1.2%) of another race/ethnicity. One hundred ninety-three were women (29.6%), 121 (17.5%) were ≥65 years, and 517 (79.3%) participated in a placebo-controlled trial. Eighty-five percent indicated being satisfied overall. Compared with White, non-Hispanic/Latino, the odds of not satisfied overall were 2.96 times higher for Black/Asian/>1 race, non-Hispanic/Latino (P < 0.001) and 0.40 times lower for Hispanic/Latino (P = 0.004). The odds of not satisfied overall was 1.9 times higher when the number of preintervention adverse events experienced was ≥1 (P = 0.012), 1.8 times higher when the percentage of the intervention duration with adverse events was >5% (P = 0.024), and 7.4 times higher for subjects who terminated the intervention early (P < 0.001). These findings can inform the design of future chemoprevention trials and help investigators improve accrual, retention, adherence, and diversity in this underexplored research setting. PREVENTION RELEVANCE: The five-item "WIWI?" questionnaire, which captures the participant-reported experience of trial participation, gives the subject a voice in the development of new chemopreventative agents. This study in 652 subjects looked at satisfaction with participation in early-phase chemoprevention trials for higher-risk, cancer-free men and women. See related Spotlight, p. 7.

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
