• Patient or Population: How would I describe a group of patients similar to mine?

• Intervention: Which main intervention, prognosis, or exposure am I considering?

•Comparison: What is the main alternative to compare with the intervention?

•Outcome: What can I hope to accomplish, measure, improve or affect?
