[2025-10-01T18:08:07.429768] [PI reasoning] **Clarifying concepts in epidemiology**

I think Tripepi 2012 might provide enough support for this concept. It mentions that prevalence is about the burden of disease in a population, while incidence refers to new cases, showing their relationship with disease frequency and exposure. We may want to cite Alho 1992 to explain the relationship, but our main point is that treatment doesn't impact incidence. For an exam-style response, I can rely on Tripepi 2012 for definitions, emphasizing that treatment affects prevalence, not incidence.
