Evidence Synthesis Center

In 2019, the Institute established an evidence synthesis center to provide a way for researchers, professionals, and students to receive guidance in performing systematic reviews. Systematic Reviews are a new form of research in Palestine. With direction from the team, they can help guide the production of high-quality research.


The Center is a member of The Global Evidence Synthesis Initiative (GESI). GESI is a network of evidence-based synthesis centers in low and middle-income countries. The network provides the possibility for centers to collaborate, provides training for capacity strengthening purposes and as a platform for funding opportunities. Our center is the only center to become a part of GESI in occupied Palestine.

Our team members have received training in evidence synthesis and implementation research, are experienced in performing systematic reviews, and are ready to provide support and guidance to anyone considering conducting a systematic review. We hope to expand our capacity strengthening activities to include implementation research soon.

For those interested in learning more about what the Center has to offer or in building their knowledge base in evidence synthesis please do not hesitate to contact us for more information.


The ICPH Evidence Synthesis Center focuses on the generation of systematic reviews and evidence synthesis in all areas related to public health. The center also provides training to strengthen the capacity of researchers to be able to perform their own research.


To become the primary evidence synthesis center in occupied Palestine with the ability to generate high-quality research as well as provide researchers, healthcare professionals, and students alike with the training needed to perform their own systematic reviews.
