From the definitions above, we immediately see that the three measures have quite different ranges; both the relative risk and odds ratio vary between 0 and ~, while the risk difference is limited to a much smaller interval between -1 and 1.

Nevertheless, there seemed to be an inverse relation between the degree of homocysteine reduction and the relative risk of stroke, with a significant reduction in the relative risk of stroke occurring once a 20% decrease in homocysteine concentration had been reached.
Meyer and Meyer explain that the coefficients of absolute and relative risk aversion developed by Pratt (1964) and Arrow (1965) were originally based on this specific concept of wealth, but because W is difficult to measure in practice, most subsequent analyses have used other forms of wealth or nonwealth variables as arguments of the decision maker's utility function.
When, in 1994, Janet Daling found that women have a 1.5 relative risk for breast cancer after abortion, the Journal of the National Cancer Institute, publishing her study, downplayed her results with an editorial noting, "In epidemiologic research, relative risks less than 2 are considered small and ...
