Q
What is the Risk Difference (RD) in epidemiology?
A
The Risk Difference (RD) is calculated as EGO - CGO and is often referred to as the absolute risk difference.
2
Q
What is the Risk Ratio (RR) and how is it calculated?
A
The Risk Ratio (RR) is calculated as EGO ÷ CGO and is usually referred to as the relative risk.
3

Why are absolute measures of risk differences preferred over relative measures?
A
Absolute measures of risk differences provide clearer information for decision-making compared to relative measures, which can be deceptive.
