Introduction to PubMed

PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. Developed and maintained by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM), PubMed provides access to a vast repository of medical literature, including research articles, clinical studies, reviews, and more. The platform is designed to help researchers, healthcare professionals, and students find relevant and reliable information to support their scientific inquiries, clinical decisions, and educational needs. For instance, a researcher studying the effects of a new drug on cancer cells can use PubMed to find all related studies, review articles, and clinical trials to gather comprehensive information and support their research.

Main Functions of PubMed

  • Literature Search

    Example Example

    A healthcare professional looking for the latest research on diabetes management.

    Example Scenario

    A doctor needs to find the most recent studies and clinical trials on new diabetes treatments to provide up-to-date care for their patients. By entering relevant keywords into PubMed, the doctor can access a list of recent articles, reviews, and clinical guidelines.

  • Access to Free Full-Text Articles

    Example Example

    A medical student needing full-text access to articles for their thesis.

    Example Scenario

    A graduate student writing a thesis on cardiovascular diseases requires access to full-text articles. PubMed provides links to free full-text articles available through PubMed Central (PMC) and other open-access sources, enabling the student to access and reference necessary literature.

  • Advanced Search Filters

    Example Example

    A researcher conducting a systematic review.

    Example Scenario

    A researcher working on a systematic review of interventions for Alzheimer's disease needs to filter articles by publication date, study type, and other criteria. PubMed's advanced search features allow the researcher to apply specific filters, narrowing down the search results to the most relevant and high-quality studies.
