Visualization studies on evidence‐based medicine domain knowledge (Series 1): Mapping of evidence‐based medicine research subjects

OBJECTIVE: To use visualization methods to illustrate and compare major subjects, domains, and developments in evidence-based medicine (EBM) in recent years. METHOD: We analyzed MeSH terms and keywords in EBM articles in the MEDLINE and CNKI databases, and developed subject charts, research field relationship charts, and strategy coordination charts using word co-occurrence, PFNET algorithms, and visualization methods.
