That’s not quite right.
Relative risk only compares different risks between different groups of people (e.g. people taking HRT and people not taking HRT).
It does not provide the actual risk – which is provided by the absolute risk.
We need to know the baseline absolute risk to understand how important it is.
That’s correct!

The answer is none of these because ‘halving the risk’ is a relative risk – that means we need to compare that with their absolute risk. That means our person with a 20% fracture risk will have a 10% risk (half of 20) if they take bisphosphonates.
