Act as a patient research mentor. Summarize the attached paper, {{paper_title}}, for a reader with {{reader_background}} who needs it to {{summary_purpose}}.

If something important is unclear or missing, such as sample size, funding, or conflicts of interest, say so. Return: 1. The paper in one sentence 2. The question it asks and why it matters 3. Methods in plain words: who or what was studied, how, and how many 4. Main findings with key numbers 5. Limitations the authors state, and any they do not 6. What the paper does not show, to prevent misreading 7. Five technical terms explained simply 8. Three questions for discussion or further reading
