LMIC Filters

Filters for PubMed (NLM), MEDLINE (Ovid), Embase (Ovid), and CENTRAL (Cochrane Library) to help identify studies relevant to LMIC.

Filters are based on the World Bank list of countries (2019), classified as low-income, lower-middle-income or upper-middle-income economies: https://datahelpdesk.worldbank.org/knowledgebase/articles/906519-world-bank-country-and-lending-groups

None of the filters have been validated.

If you would like to help improve these filters, please send an e-mail to marit.johansen@fhi.no. Any comments and suggestions are more than welcome.

The EPOC LMIC filters were developed in collaboration with colleagues at the 
WHO Library and the Campbell Collaboration.
