PubMed is a free online database operated by the US National Library of Medicine (NLM). It forms part of the National Centre for Biotechnology Information (NCBI) and is the largest and most important resource for medical literature and life sciences publications. The database contains over 30 million bibliographic records from various disciplines such as medicine, biology, chemistry, pharmacology and health sciences.

The records contained in PubMed come from various sources such as scientific journals, conference proceedings and online books. PubMed’s main database is MEDLINE, which has been indexing medical literature since the 1960s. MEDLINE contains articles from more than 5,200 scientific journals from around the world, with a focus on biomedical and health science topics.

PubMed enables users to search for scientific publications and access abstracts and, in some cases, full-text articles. The platform also offers advanced search functions that allow users to refine their search by specific authors, journals, publication dates or subject areas. PubMed is an invaluable resource for researchers, healthcare professionals, students and anyone interested in scientific information.

PubMed and microcurrent therapy

As of 7 May 2023, PubMed listed 184 entries on microcurrent therapy (keyword: microcurrent therapy). What do 184 entries in PubMed have to do with the scientific evidence?

The figure of 184 entries on microcurrent therapy in PubMed shows that this topic is being addressed and investigated in the scientific literature. However, it is important to note that the sheer number of entries does not necessarily reflect the quality or strength of the scientific evidence. To assess the scientific evidence for microcurrent therapy, several factors must be taken into account:

Quality of studies: The scientific evidence depends on the quality of the studies conducted. High-quality studies, for example, use randomised controlled trial designs, large sample sizes and rigorous methodology to minimise bias and random outcomes.

Consistency of results: If several independent studies arrive at similar results, this indicates a higher level of scientific evidence. Consistency across different studies increases confidence in the results and the applicability of the therapy.

Systematic reviews and meta-analyses: Systematic reviews and meta-analyses are studies that summarise and evaluate the results of several individual studies in order to draw an overall conclusion regarding the efficacy of a therapy. These types of study are particularly valuable as they enable a more comprehensive and objective assessment of the available evidence.

To assess the scientific evidence for microcurrent therapy, it is therefore necessary to critically review the available studies, taking into account the quality of the studies, the consistency of the results and any existing systematic reviews or meta-analyses. The number of entries in PubMed is a good starting point for gaining an overview of the field of research, but should not be used as the sole indicator of the strength of the scientific evidence.
