Comprehensive Evidence Synthesis Services
Evidence synthesis is the systematic process of combining findings from multiple primary studies to generate new knowledge, inform clinical decisions, and guide policy. It encompasses a family of review methodologies, each designed for specific research contexts and questions.
At Research Gold, our evidence synthesis service covers every major review type across health sciences, nursing, psychology, education, social sciences, and beyond. Whether you need an umbrella review for a clinical guideline, a rapid review for a policy brief, or a narrative review to contextualize your primary research, our PhD methodologists deliver rigorous, publication-ready work following established methodological frameworks. Research Gold matches you with a PhD methodologist published in your field, so the reviewer who synthesizes your evidence already knows its literature and reporting conventions.
Review Types We Offer
Systematic Review

A systematic review follows the Cochrane Handbook for Systematic Reviews of Interventions, version 6.5 (Higgins JPT, Thomas J, et al., 2024) with PRISMA 2020 reporting (Page et al., BMJ, 2021). Includes protocol development, comprehensive search, dual-reviewer screening, risk of bias assessment, and narrative or quantitative synthesis.
