"I am asking purely out of ignorance ... Correct me if I'm misunderstanding something here"

How do you think 25cf should have handled this differently?

Just ask the question. The preamble and last sentence only detract from the main point: how does your study debunk the OP's? Yours is about NSAIDs (i.e. aspirin) decreasing the risk of Alzheimer's, OP's is about paracetamol (not an NSAID) increasing the likelihood of Alzheimers.

If you're misunderstanding something, don't worry, someone will set you straight.
