Subject: boundary stat.
Здрпавствуйте!

Помогите, пожалуйста, разобраться со смыслом следующих двух предложений.

Similar to the efficacy stopping boundary, at each interim analysis, the DVC will be also guided by a futility boundary. The futility boundary will be calculated independent of the efficacy boundary and therefore non-adherence does not inflate the overall alpha.

Спасибо!
