Traditional, complementary, and integrative medicine evidence map: a methodology to an overflowing field of data and noise

This article presents a six-step evidence map methodology along with recently published TCIM evidence maps, including one related to COVID-19. TCIM evidence maps are useful instruments to inform decision-making for policymakers, health practitioners, and patients.
