Reporting on health risks can be misleading if absolute risk and the study period are not also considered.

“you never talk about a relative risk change without an absolute risk accommodating it right so so what does that look like so the the relative risk increase of breast cancer in the estrogen plus MPA group versus the placebo was 25 27 percent and that became the only headline HRT increases risk of breast cancer by 27 percent now I don't think that's true at all today but let's even look at the data what was the ARR what was the absolute risk increase it was a difference between five cases per thousand and four cases per thousand so the ARR was 0.1 percent one case in a thousand and it's true going from four and a thousand to five in a thousand is a 25 increase but it's a completely inappropriate context”
