Chapter 1: Clinical Trials of Pain Treatment: Single Dose Trials: Question 3.1

        

Do these data demonstrate Drug X is effective?

You answered:


No
  The data do not demonstrate that Drug X is an
effective analgesic in this condition.

Treatments were placebo, Drug X, and morphine.  The figure shows that both Drug X and Morphine gave a large amount of relief, similar to each other.  Both were statistically superior to placebo.

INCORRECT

These data do demonstrate that Drug X is an effective analgesic in this condition because it is more effective than the placebo.
