A common way to compare the probability of death or disease in two groups is to calculate the ratio of the measures of disease frequency in the groups. This ratio is referred to as the " relative risk " For example, if the incidence rate of breast cancer in Hispanic women is 20/100,000 compared to 45/100,000 in Black women, the relative risk (RR) for breast cancer in Black women compared to Hispanic women is 225 Black women can be said to have a 225% excess risk of developing breast cancer than Hispanic women What is the relative nsk of heart disease death in whites compared to Hispanics using the crude death rates?
