actually means in real terms for women. If this is meant to be an informative article, than it fails because it makes the mistake of in attempting to be scientifically accurate, it actually presents scientific gobbledegook. The HR is presumably a hazard ratio. Does that mean that the increased risk represents a 1.58%, or 58% increase, and an increase on what? If the chance of developing breast cancer is 50%, then is the increase to 51.8% (hardly a significant increase) or to 76% (a pretty devastating significant). On the other hand if the risk is 0.05%, then and increase to 1.85% would be pretty significant, whereas one to 0.076% would not really be significant at all.
