Scoped audit evidence
These are source- and component-level audit summaries as of 3 October 2026. Access and comparison scope can differ by report; none certifies every result or the underlying raw data.
Low back pain
- current evidence level: accepted_manuscript
Source locator: Accepted manuscript Methods pp 5–8 and Table 3 printed p 21 (PDFpage 23), visually checked; original indexed abstract retained as distinct version
Limitations: Accepted Table 3 ICC .93 and SEM 9.3% extend beyond final abstract ranges; reconcile versions before selecting a subgroup rule. AppendixA not included. Historical access claims remain unverified.
Low back pain
- verification level: accepted_manuscript
20 CNSLBP/20 healthy enrolled; 19 healthy analysed after one acute-pain exclusion. Five–ten-day intra-operator and 30-minute inter-operator retest; ICC 3,1 absolute agreement. Table 3 CNSLBP SEM/MDC: semiflex ext 24.1/66.9 and flex 9.0/25.0 intra-operator; isolated ext 22.6/62.7 and flex 5.9/16.4. Report faithfully quotes final abstract combined ranges, not these subgroup cells.
