Daily aspirin has no benefit and may be harmful for healthy older adults, study says

A study involving over 19,000 participants aged 65 and older in the US and Australia examined the effects of taking a daily low dose of aspirin. The study found no significant benefit in terms of survival rates, physical disability, or dementia when compared to a placebo. However, it identified a significant risk of internal gastric bleeding and a slight increase in cancer deaths among those taking aspirin.

How many people aged 65 and older were followed in the study?

What were the rates of physical disability and dementia in both groups?
