Clinical papers were not read directly; existing review summaries were checked. No new clinical-literature search was performed. Unverified does not mean that research is absent or that there is no effect.

## Assessment scope

- Population: Direct fitness report S01 concerns 24 inactive young adults, with 12 assigned to stairs and 12 to no training. Completion, endpoint-specific analysis, exact eligibility/baseline values and applicability to everyone are unverified. S02’s 12 lean men and 11 overweight/obese participants are separate acute populations and are not summed.
- Ingredient, formulation and route: S01 records original research conditions of 60-step ascents 3 times daily, separated by 1–4 hours, 3 days weekly for 6 weeks. Actual intensity, supervision and adherence are unlinked. Distinguish S02’s acute 15–30-second, 8-bout, 9-hour exposure; research identification is not turned into exercise instructions.
- Dose: Preserve the original 60 steps, 3 times daily, 3 days weekly and 6 weeks as research conditions only. Actual exposure variation, discontinuation, adherence and concurrent activity are unverified. No new step/frequency/time/exposure totals, calories or personal exercise doses are calculated or prescribed.
- Comparator: S01 used a no-training comparator. Actual control activity, contact and expectancy differences are unverified. S02’s uninterrupted sitting, ordinary walking, continuous stair exercise and generic bodyweight exercise are not treated as identical comparisons.
- Measured outcome: The selected endpoint is 6-week VO2peak. Distinguish between-group P=.003, the approximately 5% improvement description and missing exact effects/95% CIs. Approximately 5% is not an adjusted between-group effect. Units, test procedures, blinding, endpoint hierarchy, models, precision and clinical importance are unverified.
- Duration: The selected question concerns 6-week fitness measurement. S02’s 9-hour acute insulin/glucose AUC and post-training fitness persistence/long-term disease outcomes are separate. Preserve the original long-term outcome gap without extending findings to diabetes or cardiovascular-disease prevention.
- Questions outside this scope: Generating adjusted between-group effects, 95% CIs or clinical importance from approximately 5% wording or P=.003; Transferring S02 acute insulin/glucose findings into 6-week VO2peak effects or improvement in both fitness and glucose; Summing two experiments in S02, 12 lean/11 overweight participants or shared sheets into participant, unique-trial or independent-replication totals; Inheriting parent C50, B/S/R1/I2/EX/B2/CX or historical C54→C50 adjustment as absent subclaim values or a new verdict; Extending a short-term fitness signal in selected young adults to all ages/diseases, long-term disease prevention or safety; Combining ordinary walking, continuous stairs or bodyweight exercise as the same intervention or generating exposure totals, exercise instructions, medication changes or treatment guidance

No new effects, CIs, exposure/participant/trial totals, independence certification, grades, exercise instructions, medication changes or treatment guidance are created.
- Remaining uncertainty: External original material is unread and review of existing content remains incomplete. Original grades, scores, axes, historical verification and independence statements are not treated as new verdicts or certification.
- Referenced methods: Preserved C/E/H application conditions concerning questions, populations, interventions, comparators, reports versus studies, endpoints, denominators and harms were referenced.

## Evidence and sources

### S01

Jenkins EM, Nairn LN, Skelly LE, Little JP, Gibala MJ. Do stair climbing exercise 'snacks' improve cardiorespiratory fitness? Appl Physiol Nutr Metab. 2019;44(6):681-684. PMID: 30649897. DOI: 10.1139/apnm-2018-0675.

[PubMed](https://pubmed.ncbi.nlm.nih.gov/30649897/)

Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols, SAPs and support disclosures unread  
Findings recorded in the summary: Between-group P=.003; exact effect and 95% CI unverified  
Record level: Direct small trial for selected 6-week fitness. Preserve the original 24 participants (12/12) and P=.003. Approximately 5% wording is not an exact adjusted between-group effect; CIs, units, test methods, completion/analysis denominators and prespecified endpoints are unverified. It is not a direct report of reduced glucose or disease prevention.  
Independent replication: Parent 2996 and the fitness/glucose sheets share the same two reports. S01 concerns 6-week fitness training; S02 contains two acute crossover experiments under a different 9-hour protocol, with 12 lean and 11 overweight/obese participants in separate populations. Reports, sheets, experiments and populations are not summed into new unique-trial, participant or independent-replication totals; confirmed totals, cohort relationships and independence are unverified.

Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols, SAPs and support disclosures unread  
Findings recorded in the summary: Overweight-group insulin −16.5%, P=.036; glucose null  
Record level: Background from a different acute protocol for the selected fitness question. Distinguish 12 lean men from 11 overweight/obese participants; preserve the original 9 hours, 8 bouts of 15–30 seconds and uninterrupted-sitting comparison. Overweight-group insulin AUC −16.5%/P=.036/d=.94 and null glucose/triglycerides at P>.31 are not 6-week fitness effects.  
Independent replication: Parent 2996 and the fitness/glucose sheets share the same two reports. S01 concerns 6-week fitness training; S02 contains two acute crossover experiments under a different 9-hour protocol, with 12 lean and 11 overweight/obese participants in separate populations.

## Review criteria and methods

These are Chamgap's own application conditions, informed by the relevant sections of official methodological guidance. They do not constitute official assessment-tool certification or a new efficacy score.

- M03 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-03) · §3.1, §3.2.1–3.2.3, MECIR C5/C7/C13 · Clearly record the question, eligibility conditions and reasons for changes, and distinguish variations in interventions. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.

Sample size alone does not determine precision. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.
- M19 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-19) · §19.1.2, §19.2.1–19.2.4 · Harm questions may require different designs, populations and follow-up from efficacy questions. Case reports do not establish incidence rates. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed.

## What the statuses mean

- Met: A state used when required evidence is confirmed after user review. This production does not declare that review complete.
- Partly verified: Some information in the stored summary is linked into the table. External comparison/content review is not complete.
- Unverified: The article leaves this unverified, or required material is absent from the current stored summary. This is distinct from zero, absence or safety.
- Review incomplete: User review pending.
- Not reported: Not reported within the stored material actually read; not extended to the entire primary paper.
- Inaccessible: Means an actual access failure. Access not attempted here is not assigned this state.
- Not applicable: Not used as a substitute for an evidence gap.
- Conflicting data: Requires an observed disagreement under the same comparison criteria; not automatically judged in this production.
- Insufficient evidence for the conditions: Marks a gap in additional material required by the selected conditions; not a new efficacy grade.
