Comparing benefits of every-third-day vs. daily low-dose aspirin therapy (2001)

Follow up in 2015 with essentially the same conclusions:

"Acetylsalicylic Acid Daily vs Acetylsalicylic Acid Every 3 Days in Healthy Volunteers: Effect on Platelet Aggregation, Gastric Mucosa, and Prostaglandin E2 Synthesis"

What's the benefit of taking aspirin regularly anyways?

This could mitigate side effects (stomach ulcers, bleeding) while retaining most of the benefits.

Is there a good heuristic now for which things on nih.gov.or cdc.gov are real science?
