핵심 개념
Highly clinically cited biomedical papers have distinct advantages over medium and lowly clinically cited papers in accumulating clinical citations, both in the initial stage (from 0 to 1st clinical citation) and the build-up stage (from 1st to Nth clinical citation). Biomedical papers closer to clinical science more easily receive clinical citations than papers closer to basic science.
초록
The study explored the temporal characteristics of clinical citations of biomedical papers, including the time required to receive the first clinical citation (initial stage) and the time required to receive additional clinical citations after the first one (build-up stage). Over 23 million biomedical papers published between 1940 and 2013 were analyzed.
Key findings:
Initial stage:
- Highly clinically cited papers received their first clinical citation much faster than medium and lowly clinically cited papers. About 35% and 11% of highly and medium clinically cited papers received their first clinical citation within the publication year, compared to only 3% of lowly clinically cited papers.
- Papers closer to clinical science (e.g., clinical guidelines, clinical trials, human-related papers) received their first clinical citation more quickly than basic science papers.
Build-up stage:
- As the number of clinical citations increased, the differences in the time required to receive the corresponding number of clinical citations among the three groups of biomedical papers significantly increased.
- Highly clinically cited papers had a distinct advantage over even clinical guidelines or clinical trials in accumulating clinical citations.
The study also found that basic papers (animal- or cell/molecular-related) needed to accumulate about 47% of their total citation counts or 25 citations before receiving their first clinical citation, indicating the difficulty of clinical translation for basic biomedical research.
The proposed indicators could be useful for monitoring the translational progress of biomedical research. The findings can also help young scholars in biomedicine to gain more attention from clinical science and achieve success in their scientific careers, especially those in basic science.
