    Appendix A: Methods and literature search strategy

    Methods and literature search strategy

    NICE has identified studies and reviews relevant to corticosteroid-eluting bioabsorbable stent or spacer insertion during endoscopic sinus surgery for chronic rhinosinusitis from the medical literature. Relevant published studies identified during consultation or resolution that are published after this date may also be considered for inclusion.

    Search strategy design and peer review.

    This search report is informed by the Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension (PRISMA-S).

    A NICE information specialist ran the literature searches on 24/02/2024. See the search strategy history for the full search strategy for each database.

    The principal search strategy was developed in MEDLINE ALL (Ovid interface). It was adapted for use in each of the databases listed in table 4a, taking into account the database's size, search functionality and subject coverage. The MEDLINE ALL strategy was quality assured by a NICE senior information specialist. All translated search strategies were peer reviewed to ensure their accuracy. The quality assurance and peer review procedures were adapted from the Peer Review of Electronic Search Strategies (PRESS) 2015 evidence-based checklist.

    Review management

    The search results were managed in EPPI‑Reviewer version 5 (EPPI‑R5). Duplicates were removed in EPPI‑R5 using a 2‑step process. First, automated deduplication was done using a high-value algorithm. Second, manual deduplication was used to assess low-probability matches. All decisions about inclusion, exclusion and deduplication were recorded and stored.

    Limits and restrictions

    The CENTRAL database search removed trial registry records and conference material. The Embase search excluded conference material.

    English language limits were applied to the search in adherence to standard NICE practice.

    The date limit was included to update an earlier search for this topic.

    The limit to remove animal studies in the searches is standard NICE practice, which has been adapted from Dickersin K, Scherer R, Lefebvre C (1994) Systematic Reviews: Identifying relevant studies for systematic reviews. BMJ 309(6964): 1286.
