Suppose that we were going to conduct a study to determine if there is an decrease in risk of getting lung cancer based on whether the person eats strawberries several times a week. in the group(1 that eats strawberries regularly, we find than 5 out of 2000 get lung cancer. in the group(2 that does not eat strawberries regularly, we find that 5 out of 1000 get lung cancer. what is the sample relative risk?

Relative risk [RR] = [no of diseased patient in group 1/total no of people in the group 1] divided by [no of diseased patient in group 2/total no of people in group 2]
RR =[ 5/2000] divided by [5/1000] = 0,0025/0.005 = 0.5
Therefore the relative risk of the sample is 0.5.

Relative risk [RR] = no of diseased patient in group

1/total no of people in the group 1

divided by no of diseased patient in group

2/total no of people in group 2

RR =[ 5/2000] divided by [5/1000] = 0,0025/0.005 = 0.5

Therefore the relative risk of the sample is 0.5.

What is relative risk for a disease ?

A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group.

What do relative risk numbers mean?

An RR of 1.00 means that the risk of the event is identical in the exposed and control samples.
