The 1year risk of completed rape was significantly lower in
The 1-year risk of completed rape was significantly lower in the resistance group than in the control group (5.2% vs. 9.8%; P=0.02). The 1-year risk of attempted rape was also significantly lower in the resistance group (3.4% vs. 9.3%, P<0.001).
Calculate the relative risk of attempted rape for women in the resistance group compared to the control group.
Solution
Therefore the relative risk of attempted rape for women in the resistance group compared to the control group is given by,
RR=(3.4/8.6)/(9.3/19.1)=(3.4*19.1)/(8.6*9.3)=0.8119
| Rape vs group | Attempted Rape | Completed Rape | Total | 
| Resistance group | 3.4 | 5.2 | 8.6 | 
| Control group | 9.3 | 9.8 | 19.1 |
