SANRA Quality Self-Assessment Protocol v1

This document reports the authors' self-assessment of the manuscript using the SANRA scale — the Scale for the Quality Assessment of Narrative Review Articles (Baethge, Goldbeck-Wood, 26 Mertens, 2019; Research Integrity and Peer Review, 4(1), 5. https://doi.org/10.1186/s41073-019-0064-8). SANRA was developed to provide a brief, standardised instrument for evaluating the quality of narrative review articles across six domains. It is used in editorial decision-making, peer review, and research on narrative review quality. Authors' self-assessment using SANRA serves three purposes in this submission. First, it demonstrates methodological transparency: the scoring process requires the authors to make explicit the evidence basis for each quality claim rather than asserting quality narratively. Second, it identifies specific limitations honestly and in advance of peer review, enabling reviewers to assess how the authors have handled known weaknesses rather than discovering them as unacknowledged gaps. Third, it documents how SANRA findings informed revisions during manuscript development, providing a traceable record of methodological decision-making.
