About the Journal

เชียงใหม่เวชสาร or Chiang Mai Medical Journal (CMMJ) (Formerly Chiang Mai Medical Bulletin) is an open access and official journal of Chiang Mai University Faculty of Medicine.

Focus and scope

CMMJ accepts original papers on clinical and experimental research that are pertinent in the health sciences. Original articles, short communications, case reports, review articles, letters to the Editor, and miscellany are welcome.

Peer review process

CMMJ operates a double-blind review process. Authors may suggest peer-reviewers, which the editor may or may not use. All submitted articles will be initially assessed by the editor for suitability for the journal. Each article deemed suitable is then sent to a minimum of two independent expert reviewers to assess its scientific quality. Reviewers submit their reports to the editor using the online system. The Editor makes the final decision and informs such decision to the authors. Publication

Publication Frequency

CMMJ is published 4 issues/year (i.e., Mar, Jun, Sep, and Dec).
