Item-level audit trail of pre-Delphi amendments between the archived draft item list and the final Round 1 e‑Delphi questionnaire items (n = 114).

The table lists the final English item labels (as in Table 2), pre-Delphi amendment codes, one-line rationales, and informational source documents. PreDelphi_Amendment_Code reflects changes between the archived draft questionnaire and the final e-Delphi Round questionnaire used in the Delphi survey. ‘Source document(s)’ indicate informational inputs screened during item generation (targeted document review) and do not necessarily represent a single direct source for each item. Notes may include scope clarifications and mapping decisions made when operationalizing broad concepts from source documents into questionnaire items. Committee‑synthesized items were included where needed to reflect the Japanese clinical context. (XLSX)
