• 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?

community.
