Planning your research saves you time.
Translating your research topic into a "PICO" question will help you figure out how to search for your topic in a database. The first step is figuring out search terms for your Population/Problem, Intervention, Comparison, and Outcome.
Using the PICO Format
P Patient, Population, or Problem of Interest
I Intervention, Exposure, Prognostic Factor (treatment, diagnostic test, risk factor, etc.)
C Comparison (implicit or explicit)
O Outcome of interest (positive or negative)
