Abbreviated key title: Glob. Meta-Anal. J.

Periodicity: One Volume per year (Open Access)

 

Aims & Scope:

The Global Meta-Analysis Journal (GMAJ) is an open-access, peer-reviewed journal dedicated to advancing the science and application of meta-analysis across diverse disciplines. GMAJ serves as a premier platform for the integration, synthesis, and interpretation of quantitative evidence to inform research, policy, and practice globally.

Core Areas of Focus:

• Clinical and Public Health Research – including network meta-analyses, comparative effectiveness, diagnostic test accuracy, and systematic reviews across medical specialties.
• Environmental and Ecological Sciences – including meta-analyses of climate change impacts, biodiversity, conservation strategies, and environmental health.
• Social Sciences and Policy – including education, economics, psychology, public policy, criminology, and international development.
• Cross-disciplinary and Methodological Innovations – such as umbrella reviews, individual participant data (IPD) meta-analyses, ALE meta-analysis, Bayesian meta-analytic models, and tools for bias detection and heterogeneity assessment.

Unique Value Proposition:
GMAJ is the first journal focused exclusively on interdisciplinary meta-analysis, aiming to:

• Bridge scientific silos and encourage cross-sector synthesis.
• Leverage the inherently high citation impact of meta-analyses to accelerate indexing in Scopus and SCI.
• Serve as a hub for methodological innovation and best practices in evidence synthesis.

The journal welcomes original research articles, methodological papers, protocols, commentaries, and data papers that contribute to the rigorous and transparent integration of evidence.
