Dears in biology stackexchange community, I hope that everyone is fine.
I am using pubmed in my current review. My focus is about an application on the scope of Clinical Trial. When I used MeSH for narrowing my research scope on Clinical Trial, I got two different categories which I cannot find any clear difference between them. They are:
- Clinical Trials as Topic
- Clinical Trial [Publication Type]
However, when I search on the two different categorises, I found very different resulted papers. That means that there are a difference between the two categories where my ignorance is.
Could you please tell me what is the difference?
Possible examples of two queries: 1. ("Clinical Trial" [Publication Type]) AND "Prostatic Neoplasms"[Mesh] 2. ("Clinical Trials as Topic"[Mesh]) AND "Prostatic Neoplasms"[Mesh]
Many thanks to you for your time, in advance.
