Relative risk Flashcards
1
Q
ratio of risk in the experimental group (experimental event rate, EER) to risk in the control group (control event rate, CER).
A
Relative risk
OR relative risk ratio
2
Q
Experimental Event Rate (EER)
A
rate at which events occur in the experimental group
3
Q
Control Event Rate (CER)
A
rate at which events occur in the control group
4
Q
What does it indicate if the relative risk ratio is > 1
A
the rate of an event is increased compared to controls.
and similarly - if the risk ratio is < 1 then the rate of an event is decreased compared to controls
5
Q
How is relative risk reduction or relative risk increase calculated?
A
by dividing the absolute risk change by the control event rate
