"Although possibly not statistically different, as you say, there could still be an appreciable %RRR magnitude difference between the crestor/apabetalone and lipitor/apabetalone groups, wouldn't you agree?"

For example:

1) Crestor/apabetalone vs. Crestor/placebo. 40% RRR, p<0.05.

2) Lipitor/apabetalone vs. Lipitor/placebo, 20% RRR, not significant.

3) Crestor/apabetalone vs. Lipitor/apabetalone, not significant.
