I wholeheartedly second this KMBJN's post.

Just for clarification.
Any difference can be shown to be statistically significant with large enough trial. The difference between survival rates 67.0 % and 66.0 % at 24 months can be shown to be statistically significant with a really large trial (~ 40000 subjects). But is the difference clinically meaningful?

Conversely. Most of us would agree that 138 % difference in response rates is clinically meaningful. But it will not be statistically significant in a trial with 60 subjects. As we have seen in prurisol 2a trial.
