One of the search features in the TRIP Database is the ability to search by the PICO method.
PICO allows users to search using a structured clinical question which can include any or all of the following 4 elements:
P - Problem/Population/Patient (eg alcohol dependent women)
I - Intervention (eg the name of a treatment, medication or diagnostic test)
C - Comparison (eg a comparison of the Intervention with another type of treatment or intervention)
O - Outcome (eg lower mortality or relapse)
