Hi ElMaestro,

❝ For once I actually disagree with Helmut. At least, I think I do if I got his post right.

Only one greek letter in my post. I have written there:

❝ Doing the math is just the first step. Before you pool CV I would suggest to inspect whether the confidence intervals of the CVs overlap […]. If not, try to find out why (different CROs, populations, bioanalytical methods, …). Use common sense to decide which CVs are reliable enough to pool.
