The second step is allocation concealment by development and allocating concealment mechanism (sequentially numbered, sealed, opaque envelopes) followed by preparation of the allocation concealment mechanism using the sequence from step one.
Before the start of the trial, the study coordinator, who was not involved in the selection and inclusion of patients, organised the preparation of numbered, opaque, sealed, and tamper-proof envelopes containing the treatment allocation.
Prior to the start of the trial, the trial coordinator, who is not involved in the selection and inclusion of patients, will supervise preparation of numbered, opaque and sealed tamper-proof envelopes containing the treatment allocation.
Once the caecum had been reached and appropriate bowel preparation confirmed, an opaque sealed envelope with sequential numbering was opened and participants were allocated to either NBI or conventional colonoscopy withdrawal of the instrument.
A person who is not in contact with the patients in any other way is responsible for the preparation of an abundant number of opaque envelopes containing the randomisation result, and this person randomises the patient by opening the envelope.
The pharmaceutical preparation will be directly sent to participating centres in closed, opaque and consecutive numbered bags by the central pharmacy.
To identify the genes responsible for the in vitro and in vivo phenomena described above, we cross-compared RNA preparations from sessile and/or planktonic cultures from transparent and/or opaque bacteria by microarray analysis.
