Claim Protocol ID: protocol_demo_study_time_reduction_v0_3 · Dataset snapshot: aftelo-demo-study-snapshot-2026-08-04-v1 · Engine: aftelo-evidence-engine-v0.4 · Calculated-record revision: study-v0.1 · Audit reference: demo-study-audit-v0.1.
Preregistered question
Among eligible participants, does the fictional tool reduce median styling time by at least 30% at Day 30?
Fictional cohort and recruitment
312 enrolled adults; 286 eligible after prespecified screening; recruited through a disclosed creator invitation and a neutral research panel.
Endpoints
Primary: median paired Day-30 styling-time reduction. Secondary: participant-reported claim state, continued use, returns, abandonment, and Day-90 retention.
Verification mix
211 Day-30 complete; 168 Day-30 complete and purchase verified; 241 purchase verified across the eligible cohort; 198 usage verified; 143 completed two follow-ups. Fixed completion honorarium was unrelated to sentiment.
Primary-analysis cohort flow
Day-30 completed 211 → complete and purchase verified 168 → missing paired timing −14 → protocol exclusions −3 → manipulation-review exclusions −2 → primary analysed cohort N=149. Each exclusion is mutually exclusive and applied once.
Calculation configuration
Primary estimate: 28% cohort-median paired reduction. Primary analysed cohort: N=149. Deterministic seed: 20260804. Bootstrap resamples: 10,000. Percentile interval: 23.4%–32.1%.
Checkpoint and attrition
Day 7: 248 completed; Day 30: 211 completed; Day 90: 143 completed. By Day 90: 36 not yet due, 14 withdrew, 11 returned, 9 protocol-excluded, 7 invalidated, 66 eligible/no response.
Primary and secondary findings
Claim threshold: at least 30%. The deterministic fictional paired bootstrap 95% interval includes the threshold, so the final decision is Inconclusive. The descriptive participant distribution is reported separately: 59% held up, 24% partly held up, 17% did not hold up.
Paired and cross-sectional results
Same 143 Day-30/90 participants: held up 61%→52%; partly held up 23%→27%; did not hold up 16%→21%; still using 72%→57%. Cross-sectional totals are presented separately.
Returns, abandonment, and audience fit
Day-30 returns: 11%; stopped use: 13%. Fictional fit segment: thick or long hair, 64% held up, n=58 completed, 48 purchase verified, 68% completion, Emerging evidence.
Uncertainty and limitations
Self-reported timing, creator-invitation selection, missing follow-ups, no comparator, and limited subgroup precision prevent causal claims. No conclusion is generalized beyond the stated cohort.
Sponsor, method, and corrections
Fictional sponsor: Example Tools Ltd. Sponsor had no outcome-editing right. Methodology v0.3. Correction history: study-v0.1 published August 4, 2026; no earlier calculated revision exists. The fictional report artifact is inspectable in this page; no live download or study operation is claimed.
Plain-language conclusion: this fictional study would report: point estimate below threshold; the available interval includes the threshold, so the final decision is Inconclusive, while preserving the separate participant-reported result. Sponsor disclosure remains permanent and methodology is Methodology v0.3.
