Assessment scope

Stored-material review date: Not recorded
Original evidence cut-off: 2026-09-07
Scope actually checked: Existing review summaries and stored records of methodological application. Full papers, supplements, registrations, plans and original data were not read.
What the dates mean: This is the date the stored materials were checked, not the date of a new search of the clinical literature.
Population: Core S01 Maeda 2023 is a home crossover trial with 23 adults. Exact ages, sex, insomnia diagnoses, eligibility, recruitment and condition-specific analysis/completion denominators are unverified. Older women with insomnia and nine participants in original S02 Dorsey 1996 bibliography are a separate supporting context; another nine-person mention is unlinked to bibliography. Participants/nights are not added together.
Ingredient, formulation and route: Original S01 distinguishes 40°C shower alone, shower plus about five minutes of bathing and shower plus about 16 minutes. Chest-level immersion, mean long-bath exposure of 16.1 minutes and ending 1.5–2 hours before bed identify study exposure. They are not bathing, sleep or treatment instructions.
Dose: Temperature, immersion, bathing duration and pre-bed interval are preserved only as original study exposure. Mean long-bath exposure of 16.1 minutes and sleep onset of 16.1±13.9 minutes after the short bath are different values. Individual distributions, temperature maintenance, interval adherence and actual deviations are unverified; no new doses, total times or schedules are calculated.
Comparator: An active control that already received a 40°C shower. Original categorization as no bath does not mean no heating or no intervention. There was no shower-alone versus no-heating comparison, so results are not transferred into shower efficacy.
Measured outcome: The selected outcome is actigraphic sleep-onset latency (SOL). Retain shower 20.3±14.3 minutes, short bath 16.1±13.9, long bath 12.3±10.1, long-bath versus shower P<.05, original simple mean difference −8.0 minutes and subclaim note of eight minutes. Exact within-person estimands, 95% CI, meaning of ±, prospective primary outcome and models are unverified. Null condition differences in sleep efficiency of 78.69%, 80.30% and 82.05%, and perceived sleep quality, are separate.
Duration: The original records three conditions in randomized order over approximately three weeks, analyzing one qualifying night per condition. Distinguish single exposure, selected nights and the operational period; this is not extended into daily three-week treatment, long-term effects or insomnia treatment.
Questions outside this scope: Converting active shower control into no heating/no intervention or establishing shower-alone efficacy; Mixing mean bath exposure of 16.1 minutes with short-bath sleep onset of 16.1 minutes, or arbitrarily classifying ± as SD, SE or CI; Turning original simple −8.0 minutes into new arithmetic, crossover-adjusted effects or CIs, or SOL signals into SE, perceived quality or insomnia-treatment success; Treating one selected night as all nights/complete analysis of all 23 people, or adding participants/nights; Using supporting Dorsey nine-person and another unlinked nine-person mention as exact independent confirmation, new reports or participant totals; Inheriting parent C46, axes or historical checks as subclaim scores/completed current review, or creating bathing, sleep, treatment or procedure instructions

Conditions for verification: Material for Separate source disclosures of support, employment and interests must be linked to the selected subclaim, parent context, same report/trial, outcome units, times, actual comparator and denominators, distinguishing unread external material.
Why this condition is needed: This condition connects Separate source disclosures of support, employment and interests with sleep-onset latency after a long bath, active shower control, exposure versus outcome duration, crossover order, selected nights, sleep onset versus efficiency/subjective measures, denominators and harms.
Application exceptions: Preserve original numbers, ±, P values and study exposure only. Distinguish mean bath exposure of 16.1 minutes from short-bath mean sleep onset of 16.1 minutes, active shower control from no heating, simple mean differences from within-person adjusted effects, one selected night from the operational period, sleep onset from efficiency/subjective quality, and the core report from supporting bibliography/unlinked mentions. No new arithmetic, effects, CIs, hypothetical numbers, grades, independence certification, bathing/sleep methods, treatment or procedure instructions are created.
Referenced methods: Preserved C/E/H application conditions concerning questions, populations, interventions, comparators, reports versus studies, endpoints, denominators and harms were referenced.

N26 · How far is bathing safety verified?

Current findings: The parent's original safety value is Unknown, with systematic adverse-event denominators and rates unverified. Burns, dizziness and falls are generalization-limit wording in the stored account, not observed event rates.
Verification status: Unverified
Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols, SAPs and support disclosures unread
Why unverified: The selected claim, parent material and reports are distinguished and transferred from the stored summary. Detailed original material is unverified and review of existing content remains incomplete. This does not establish completed clinical review or certification.
Reason for missing information: Condition-specific event definitions, collection, denominators, discontinuation, vulnerable populations and long-term safety are unverified.
Required materials and conditions: Harm-event collection, exposures, denominators and discontinuation
Materials to obtain first: Condition-specific event definitions, collection, denominators, discontinuation, vulnerable populations and long-term safety are unverified.
Further research: Material needed: Condition-specific event definitions, collection, denominators, discontinuation, vulnerable populations and long-term safety are unverified. This records needed materials; no new research was executed.

N27 · Are parent values, subclaim grade and historical dates distinguished?

Current findings: Parent C46, B/S/R1/I1/EX/B2/CX, four false flags and an empty override are preserved alongside the subclaim C and note. Original Korean/English, 2026-09-07, an empty correction array, an empty deliberation string and historical original-table checks do not become current reading, completed content review or a subclaim score.
Verification status: Partly verified
Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols, SAPs and support disclosures unread
Why unverified: The selected claim, parent material and reports are distinguished and transferred from the stored summary. Detailed original material is unverified and review of existing content remains incomplete. This does not establish completed clinical review or certification.
Reason for missing information: A subclaim score, status and axes, external details of historical checks and new corrections are unverified.
Required materials and conditions: Parent C46, subclaim C, axes and correction history
Materials to obtain first: A subclaim score, status and axes, external details of historical checks and new corrections are unverified.
Further research: Material needed: A subclaim score, status and axes, external details of historical checks and new corrections are unverified. This records needed materials; no new research was executed.
