Findings recorded in the stored summary: 9.3 versus 14.4 days; mean difference −5.1 days; IRR0.51 (0.26–0.99), P=0.048. Original means and differences and IRR are different measures. Do not use the IRR CI as the mean-difference CI or newly calculate differences, ratios, missingness, or prices.

Study overlap and independent replication: S01, the SWAP paper, and S02, the ISRCTN52269669 registration citation, concern the same 6-practice UK cluster trial. Distinguish 338 participants, 158/180, prespecified four-month questionnaire-reported absence, and 12-month follow-up context. Retain unverified four-month response and attrition, cluster-model details, and the different measures of mean difference and IRR; do not count the registration citation as a new clinical trial. Report and material entries are not totals of unique clinical trials, participants, or independent replication; unique totals remain null. Original replication and independence axes and past narratives are not retroactively certified as current identity or independence verification. S02 cites the ISRCTN52269669 SWAP registration and links to the same trial as S01 and the first original evidence entry. Primary absence and prospective registration in the original short citation summary are preserved summaries; actual registration and change history have not been read in this work. No clinical effects, people, or independent trials are added. Report and material entries are not unique clinical totals, and historical axes and narratives do not certify current identity or independence. S03 MI-NAV6 months and S04 MI-NAV12 months are linked as time-point reports of the later MI-NAV trial in the original text. S03 gives only ‘MI-NAV participants’ for sample size; S04's 509 is not automatically transferred. Null six-month stratified advice and positive 12-month results for both interventions concern different time points and are not new identical direct replication of SWAP4 months. Report and material entries do not establish unique clinical totals, which remain null, and historical axes and narratives do not certify current identity or independence. S04 MI-NAV12 months gives 509 participants and separate stratified-advice and motivational-interviewing values, each versus usual case management. Link it to S03's six-month context for the same MI-NAV trial; exact connections of observation, denominators, and models by period remain unverified. Do not add 509 participants, the two interventions, or different time points as independent trials or participants. Report and material entries do not establish unique clinical totals, which remain null, and historical axes and narratives do not certify current identity or independence.

Null six-month stratified advice and positive 12-month results for both interventions concern different time points and are not new identical direct replication of SWAP4 months. Report and material entries do not establish unique clinical totals, which remain null, and historical axes and narratives do not certify current identity or independence. S04 MI-NAV12 months gives 509 participants and separate stratified-advice and motivational-interviewing values, each versus usual case management.

N25 · Is the result extended to vocational rehabilitation generally, other settings, or action instructions?

Current findings: The original text restricts the result to the specific early stepped physiotherapist service in UK primary care and does not extend it to a universal benefit of all vocational rehabilitation.
Verification status: Partly verified
Materials actually read: Summary read; external material unread
Why unverified: Only the relevant information from the stored summary is recorded. Detailed original materials have not been read, and the original content review remains incomplete. Direct identical outcomes for other programmes, settings, and occupations are unverified. Do not create instructions for rehabilitation, return to work, work adjustments, treatment actions, devices, or exercise. The original content review remains incomplete.
Reason for missing information: Direct identical outcomes for other programmes, settings, and occupations are unverified. Do not create instructions for rehabilitation, return to work, work adjustments, treatment actions, devices, or exercise.
Required materials and conditions: Specific early service, countries, delivery and occupations, and original scope
Materials to obtain first: Separate populations, services, and occupational-setting materials
Further research: Distinguish the original service from the scope of extension questions. This is a proposal; the record notes that no new research, calculation, or trial was performed.
Remaining uncertainty: This record links preserved-summary statements; it does not establish external-paper comparison, a new efficacy verdict or completed content review.
Conditions for verification: Relevant original materials and analysis scope for Specific early service, countries, delivery and occupations, and original scope must be provided so unverified matters can be distinguished. The stored wording is linked here, and the original content review remains incomplete.
Why this condition is needed: This production item distinguishes Specific early service, countries, delivery and occupations, and original scope to connect materials required for the selected question with currently available materials.
Application exceptions: Limited to the stored summary for the selected formulation, population, endpoint and period. It does not substitute for numbers from other formulations/trials/endpoints or unread external material.
Referenced methods: M03 §3.1, §3.2.1–3.2.4 provide principles for clarifying questions; detailed separation rules are our own design; M04 §4.6.1–4.6.2, M15 §15.3.1; our own application; M03 §3.2.1–3.2.4; details of dose, duration, and effect modification are our own design

N26 · What history is recorded by parent B72, axes, Korean and English text, dates, and empty corrections?

Current findings: Preserve parent B72, Unknown safety, unrecorded precision and false flags, empty grade-override reasons, Korean and English text, 2026-08-26, empty corrections and deliberation, and the past cross-check in the complete stored summary.
Verification status: Partly verified
Materials actually read: Summary read; external material unread
Why unverified: Only the relevant information from the stored summary is recorded. Detailed original materials have not been read, and the original content review remains incomplete. This is not a current search, correction or retraction verification, completed content review, or certification of subclaim scores, axes, or independence. The original content review remains incomplete.
Reason for missing information: This is not a current search, correction or retraction verification, completed content review, or certification of subclaim scores, axes, or independence.
Required materials and conditions: Selected B grade, parent values and null and false and empty values, and past cross-check
Materials to obtain first: Corrections, user comments and supplied original materials
Further research: Separate the original version from production and change events. This is a proposal; the record notes that no new research, calculation, or trial was performed.
Remaining uncertainty: This record links preserved-summary statements; it does not establish external-paper comparison, a new efficacy verdict or completed content review.

Why this condition is needed: This production item distinguishes Selected B grade, parent values and null and false and empty values, and past cross-check to connect materials required for the selected question with currently available materials.
Application exceptions: Limited to the stored summary for the selected formulation, population, endpoint and period. It does not substitute for numbers from other formulations/trials/endpoints or unread external material.
Referenced methods: M04 §4.5, §4.6.3; current material-conversion limits reflect review scope and our own design; M04 §4.6.3, M15 §15.3.1–15.3.3; status distinctions are our own design
