Subject: blinding - это неосведомленность? Контекст:Observation bias was avoided by study randomization and blinding. Neither the patients, the investigators, nor the persons responsible for randomization, data monitoring, or statistical analyses knew the assignment of the patient to the 2 treatment arms until the official unblinding. Because of the different modes of application, the so-called doubledummy technique was used. The dummy tablets were visually indistinguishable from the MTX tablets. But, for technical reasons, the dummy prefilled syringes could not be ade visually indistinguishable from the MTX prefilled syringes. In order to make the color difference between the placebo and the MTX solutions less apparent, a large transparent yellow label was applied to the body of the syringe. Nevertheless, it was assumed that since the patients were MTX-naive, this would not influence their study blinding. To ensure blinding of the investigators and monitors, these persons were prevented from seeing or having contact with the prefilled syringes during the course of the study. At each study center, a designated person who was independent of the study investigator was responsible for management of the trial medication (receipt, dispensing, documentation, and return) as well as contact with the patients concerning matters related to the trial medication. Moreover, the syringes were sealed into white cartons, and patients were given cartons with unbroken seals. To ensure blinding of the trial monitor, drug accountability data were checked onsite by a different person. Мой вариант перевода: |
