Suggested answer to exercise: Nasal diamorphine, 2

Question 2: Is it correct to conclude that pain scores were no different after 30 minutes?

Suggested answer

We cannot correctly conclude that pain scores were no different after 30 minutes. The difference is not significant, but this means that we have not shown that there is a difference, not that we have shown that there is no difference.

In fact a very small difference can be seen in the data, the intramuscular group reporting more pain than the nasal group.
