In Ovid Medline, you can limit your search to clinically sound diagnosis articles and reports
After running your initial search query, click the “additional limits” option to select a limit from the resulting window.
From the resulting window, go to the “Clinical Queries”.
There are nine categories of “clinical queries” provided. Select the appropriate diagnosis category. The emphasis may be Sensitive (as in most relevant articles but probably some less relevant ones), Specific (as in mostly relevant articles but probably omitting a few), or Optimized (as in the combination of terms that optimizes the trade-off between sensitivity and specificity).
Next, click “Limit A Set”.
The new set of citations reflects the limit: clinically sound diagnosis articles and reports to your topic. Next, click on “Display” to view the results
