As the overriding components of discourse, metadiscourse markers (MDMs) have been studied extensively through varying disciplines and paradigms and in different languages/cultures. However, when it comes to subdisciplinary realization of these features, particularly in medicine, we have to seemingly pave a long way. Identifying this gap, the present corpus-based study which is inspired by the metadiscourse taxonomy of Hyland (2005), focuses on exploration of 180 Medical Physics and Nursing research articles (RAs) as two rather distinct but comparable subfields of medicine across the quantitative and qualitative paradigms in English. It is expected that the findings will help in heading off the problems of the academic researchers and graduate students in writing RAs.
