First attempt to try Med Diet in a statin world...

My comment is a question.  
1 in the analysis of the different subsets of patients you found that med diet works especially in dyslipidemic patients  
2 can you give us the reason why you don't try the null hypothesis in patients receiving statins?  
TY for your great work and answer.

I think that the answer to that question may improve our management of patients at risk. Indeed we do not know if med diet and statins do prevent better cv diseases than each of the "treatments" alone.
