valid assessment necessary for deriving the primary endpoint pharm.

[Natuli]

Подскажите, пожалуйста, как здесь перевести "valid assessment "?
Per Protocol analysis set includes subjects without any major protocol violations that may affect the primary endpoint. Moreover, subjects must be exposed to Х for the full treatment period and must have a valid assessment necessary for deriving the primary endpoint. Subjects in the PP set will contribute to the evaluation “as treated”.
