AI-use statement:
The PubMed search strategy was drafted with the PICO search builder. It used the large language model claude-opus-5-5 (Anthropic; accessed October 29, 2026) to propose search concepts and terms from the review question. The tool made 1 call to the model at high effort (the draft); claude-opus-5-5 was requested and answered it. A refusal fallback was enabled (had the model declined a request, the API could have run it again on another model Anthropic recommends); it was not used. Every MeSH heading, Supplementary Concept and publication type the strategy searches was checked against NLM MeSH (id.nlm.nih.gov) before use: 10 valid. Each numbered line was run in PubMed through NCBI E-utilities between October 28, 2026 and October 29, 2026, and PubMed's own diagnostics (phrases not found, ignored words, lost truncation) were checked. A searcher must review the strategy before it is used. The prompts, the model output and every version are in the provenance file (JSON export).
