What does a Hazard Ratio (HR) of less than 1 indicate?

  1. Poorer survival in treatment group

  2. Better survival in control group

  3. Event rate in treatment group is lower

  4. Event rate in control group is higher

The correct answer is: Event rate in treatment group is lower

A Hazard Ratio (HR) of less than 1 indicates that the event rate in the treatment group is lower compared to the control group. This means that the treatment group has a lower risk of experiencing the event being studied. Options A and B are incorrect because they involve comparing survival rates, which is not the same as comparing event rates. Option D is also incorrect because it suggests that the control group has a higher event rate, which is opposite to what a HR value of less than 1 indicates.
