English to German Medical Medical: Pharmaceuticals Title of a clinical study

They didn't use the term "treatment arm", though to me this seemed the most logical interpretation.
Anybody can confirm "Crossover-Studie mit 2 Behandlungsarmen" or has already experience with this concrete term??
Thanks a lot in advance.
