A risk estimate always has a horizon
A short idea drawn from Outlive: The Science and Art of Longevity by Peter Attia.
A statement such as “ten-year risk” contains a clock, a population and an outcome definition. Change the time window and the number may change; change the population and a model may travel poorly. Relative risk and absolute risk can also tell emotionally different stories about the same data.
This is not a method for interpreting personal results. Clinical decisions require validated tools, harms, benefits and individual context. It is a reading observation: whenever a health percentage appears, look for its denominator and horizon before treating it as a property of a person. Risk is a structured estimate, not a substance stored in the body.
