Fictional demo Outcome Study · noindex
Luma Arc styling-time claim
Preregistered question
Did the stated styling-time threshold hold at the Day-30 primary endpoint for the eligible, purchase-verified cohort?
Endpoints
Primary: Day-30 raw styling-time reduction. Secondary: reported claim state, continued use, returns, and Day-90 follow-up.
Eligibility and recruitment
Fictional demonstration cohort recruited through a disclosed creator invitation; no live recruitment, selection, or outcome data is represented.
Verification mix
Report would state reported, purchase-verified, usage-verified, and longitudinally verified denominators separately.
Checkpoint denominators
Report would show eligible, invited, completed, missing, returned, withdrawn, excluded, invalid, and not-yet-due states at each checkpoint.
Paired and cross-sectional
Same-person Day-30/Day-90 transitions appear only when source records contain paired outcomes; otherwise the report marks them unavailable.
Attrition and discontinuation
Returns, stopped use, no response, and protocol exclusions remain separate; they are never combined into a favourable completion rate.
Limitations and corrections
The report identifies missing measures, selection limits, unverified use, methodology version, sponsor disclosure, and a dated corrections history.
Sponsor disclosure: fictional example only; no sponsor funded this demo. Methodology: v0.2. Corrections history: initial fictional example published July 21, 2026.
