PICO Research Questions

Use the PICO acronym to help you form a research question. These categories will help you consider all the angles of your topic and come up with keywords to use when searching in a database. 

P: Patient, Population, or Problem

I: Intervention (or Exposure) 

C: Comparison (or Control)

O: Outcome 

Note that you might not have a C, or your C might be the absence of your Intervention. Considering the Comparison will still help you search for your topic.
