The phrase "allocation of the envelope" is correct and usable in written English.
It can be used in contexts related to distributing or assigning resources, tasks, or items, particularly in administrative or organizational settings.
Example: "The allocation of the envelope for the project materials was discussed in the meeting to ensure everyone received their share."
Alternatives: "distribution of the envelope" or "assignment of the envelope".
However, recruitment staff are unaware of the allocation until the envelope is opened in front of the participant.
Research personnel who enrolled participants and assigned interventions (AM and TRHR) were unaware of the allocation until the envelope was opened in front of the patient.
The envelopes were closed and non-transparent, making it impossible to identify the allocation before the envelopes were opened.
To prevent any violations of the allocation concealment, the envelopes could only be accessed by two study personnel who were not involved in their preparation.
To ensure treatment allocation concealment, just prior to the procedure the treating radiologist contacts a central receptionist who provides the appropriate opaque sealed envelope containing the treatment allocation of the participant according to their identification number.
After revealing the content of the envelope, both patients and physiotherapists are aware of the allocation and the corresponding treatment.
The allocation of the individual study group was then made known when the envelopes were unveiled.
Here the numbered contents of these identical envelopes reveal the study allocation of the participation.
An independent monitor not involved in further conduction of the study made new sealed envelopes according to group allocation of the withdrawn patients.
The examining clinician manages the hand over of the envelope to the participant, but is masked to the treatment allocation when determining eligibility to randomization.
Until the opening of the seal of the envelope, both the supervisor/researcher and the mothers were kept blind to the allocation of the intervention sequences.
