Search using any PubMed search terms you like — from a couple of keywords to the most complex search you can manage.
Examine a random sample of the citations returned by your search and sort them into "Good" and "Bad" piles. Good items will make up your validation set!
PubMed Search tester now uses that validation set to automatically test successive iterations of your search strategy until you are satisfied with the balance of sensitivity and precision.
"Good" documents: 0
"Bad" documents: 0
Skipped documents: 0
