question 6

Multiple Choice

Consider the data table showing patients in a trial in which 30 are given a placebo and 20 are given an experimental drug and the deaths are recorded over a period of 24 months.
​
$\begin{array}{c}\underline { \text { Control} } \quad \quad \quad \quad \quad \quad \quad \quad\underline { \text { Exp. drug}}\\\begin{array}{cccc}\text { Time } & \text { \# at risk } & \text { Deaths } & \text { \# at risk } & \text { Deaths } \\3 & 30 & 5 & 20 & 1 \\6 & 25 & 6 & 18 & 2 \\9 & 19 & 3 & 16 & 1 \\12 & 16 & 3 & 15 & 2 \\24 & 13 & 2 & 13 & 1\end{array}\end{array}$
-Based on the ?² value from a test of the hazard ratio for the control group relative to the drug treatment group, what is our conclusion?

• A) P < 0.05, the survival curves are the same.
• B) P < 0.05, the survival curves differ from each other.
