Pubmed Clinical Queries (CQ) eliminates everything that isn’t evidence, like editorials or history, and lets you focus in on clinical research. It does that by using search hedges, or filters, that limit to a specific clinical study category and scope. Click here for more about the filters themselves
There are five filters to match 5 types of clinical questions: Etiology, Diagnosis, Therapy, Prognosis and Clinical Prediction Guidelines.
You can limit to a Narrow specific search or a Broad more sensitive search.
CQ also has a Systematic Review Filter and a filter for articles that focus on Medical Genetics. The default is All for Medical Genetics but you can limit to more specific topics.
When you find a good article there is an option to see “Similar articles.” If you chose those you will no longer be using the evidence filters of CQs but the algorithm can be really helpful
