Randomization and allocation concealment procedures
To ensure homogeneity between the groups, randomization was matched and conducted by an independent statistician who did not know the participants, using a 1:1 ratio and stratified according to mammographic density (A, B, C e D). The sequence random generation was maintained in sequentially numbered, opaque, and sealed envelopes. One researcher informed the participant by phone to which group they were allocated before the schedule of the MRI exam.
