Some Studies That I Like to Quote

PICOS

Use PICOS to develop a clear idea what information you are seeking. PICOS was developed by faculty at McMaster University.

P Population/Patient/Problem For which group do you need information?
I Intervention What medical event do you need to study the effect of?
C Comparison What is the evidence that the intervention produces different results than a different or no intervention?
O Outcome What is the effect of the intervention?
S Setting/Study Type Where is the research done (e.g., ambulatory setting) or type of study (e.g., RCT)?
T Time What are the time factors?
