equivalence margin 

EVIDENCE-BASED MEDICINE

A term of art referring to the maximum tolerance or amount that 2 distinct therapies (are allowed to) differ, a value that is often indicated by the symbol δ.

In an equivalence trial, if the effects of the 2 treatments differ by more than the equivalence margin in either direction, then equivalence does not hold.
