The EPPI-Centre’s inclusive philosophy is expressed in its work supporting review teams conducting systematic reviews for and in low- and middle-income countries. This work began in 2007, when the Alliance for Health Policy and Systems Research, now hosted by the World Health Organisation, awarded grants to four institutions in low- and middle-income countries to establish centres for systematic review of health policy and systems research. The EPPI-Centre has been offering training and support to these centres since then.
