Question

You conduct a study and find that the RR for the risk of exposure on disease is 1.51 (95% CI: 0.94, 2.43, p=0.15). Which of the following statements is supported by the previous sentence (choose the single best answer)?

1) The probability that the null hypothesis is true is 0.15

2) The alternative hypothesis is false.

3) The risk of disease among the exposed is 1.51 times the risk among the unexposed.

4) The risk of disease among the exposed is 1.51 times higher than the risk among the unexposed.

Explanation / Answer

option 3 is correct

relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group

RR for the risk of exposure on disease is 1.51

it means

The risk of disease among the exposed is 1.51 times the risk among the unexposed.

A relative risk of 1.51 means you have a 51% higher risk than average
