Randomization:
In this parallel randomized clinical trial study, taking into account that not all patients are included in the study at the same time, and the researchers cannot predict which group each patient will belong to, in order to assign each patient to one of the two groups, the block randomization method will be used. In order to hide the random assignment, the codes created by the software will be placed in opaque envelopes so that it is not clear which group the next person will be assigned to.
In this study, the eligible participating patients, after receiving informed consent, according to the block randomization protocol (produced by Random Allocation Software) were allocated to one of the two control and intervention groups with a ratio of 1:1 and in blocks of 6 in such a way that the researcher cannot predict which group the next person will be placed in. The codes will be placed in the opaque envelopes, and with the entry of each new person, the envelope will be opened and the person's belonging to the relevant group will be determined.
Allocation Concealment:
In order to hide the random allocation, the codes created by the software will be placed in opaque envelopes so that the next person to be assigned to each group is not known.
Based on the sample size of this study, a number of opaque envelopes (to avoid clarity of the contents of the envelopes) are prepared and each of the random sequences created is recorded on a card and the cards are placed inside the envelopes in order. In order to maintain random order, the outer surface of the envelopes is numbered in the same order. Finally, the lids of the envelopes are glued and placed in a box. At the beginning of registration, based on the order of entry of eligible participants into the study, one of the letter envelopes will be opened in order and the allocated group of that participant will be revealed.
