| I | Intervention, Prognostic Factor, or Exposure | Which main intervention, prognostic factor, or exposure am I considering? |
| C | Comparison or Intvervention (if appropriate) | What is the main alternative to compare with the intervention? |
| O | Outcome you would like to measure or achieve | What can I hope to accomplish, measure, improve, or affect? |
