PRISMA-Compliant Methodological Protocol for Non-Clinical Systematic, Scoping, Meta-Analysis and Structured Review Studies

This record describes a general, PRISMA 2020–compliant methodological protocol for conducting non-clinical systematic reviews, scoping reviews, meta-analysis, and structured narrative reviews.

The protocol defines standardized procedures for eligibility criteria, literature search, independent dual-reviewer screening, data extraction, quality assessment, and evidence synthesis. It is intended as a reusable methodological backbone and may be cited across multiple manuscripts, with context-specific adaptations reported transparently.

The protocol involves secondary analysis of published literature only and does not include human participants or clinical interventions. PROSPERO registration is therefore not applicable.
