A Tokyo pediatrician is working to promote "evidence-based medicine" and ensure that medical treatments used in Japan are backed by the highest-quality international research.

Rintaro Mori, 44, is co-director of the Japanese branch of the Cochrane Collaboration, an international nonprofit organization that aims to produce credible health information based on research.

For around 20 years, the group, named after British medical researcher Archie Cochrane, has been the organizer of the "Cochrane Reviews," which seek to identify the most effective treatments through rigorous analysis of medical research.
