Use this scale to help put relative risk in perspective. Keep in mind that risk seems greater when put in terms of relative risk. A 100 percent increase in risk may seem enormous, but if the risk began as 1 in 100 people, the risk is increased to 2 in 100. To some people, this will seem like a large increase in risk. Others will see this as negligible. You and your doctor have to decide what levels of risk are acceptable to you.
