Pro Tips for Choosing Your Topic

• Use the PICO (Population, Intervention, Comparison, Outcome) framework to narrow your medical topic.
• Ensure your topic sentence contains a 'claim' rather than just a medical fact to allow for analysis.
• Check the level of evidence (e.g., meta-analysis vs. case report) available for your topic before committing.
• Avoid overly broad terms like 'cancer'—specify the histology, stage, and specific treatment modality.
• Align your topic with current controversies in clinical practice guidelines to ensure relevance.
