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:

GMAJ welcomes submissions that apply rigorous meta-analytic methodologies in areas including, but not limited to:

• Health and Clinical Sciences: Network meta-analyses, comparative effectiveness research, diagnostic test accuracy, intervention reviews, and systematic reviews across medical specialties and public health.
• Environmental and Ecological Sciences: Meta-analyses addressing climate change, biodiversity, sustainability, conservation strategies, and environmental health impacts.
• Psychology, Education, and Social Sciences: Evidence synthesis in behavioral sciences, learning sciences, social policy, criminology, and international development.
• Economics, Business, and Finance: Reviews evaluating financial models, policy interventions, labor trends, and economic impacts across sectors.
• Engineering and Technology: Meta-analyses related to industrial processes, technology performance, human factors, and innovation systems.
