English to Romanian Medical Medical (general) clinical trial, double blind, rheumatoid arthritis

Un context posibil:
The company submission states that this was a blinded study, in which the study sponsor, investigators, and patients were all unaware of the patient's trial arm. A dual assessor approach was employed in which an efficacy assessor only had access to efficacy data while a safety assessor "had access to all clinical and laboratory (safety) data and was able to make any necessary changes to the patient's medical therapy, thus minimizing the chance of unblinding of the efficacy assessor who only had access to efficacy data". Radiographic assessments were collected and scored by two independent readers blinded to treatment assignment and time point.

Ceva de genul "doi evaluatori"? Mulţumesc anticipat.
