- Masking Details
- After recruiting patients who met the inclusion criteria, the intervention was randomly allocated to either the right or left side using the permuted random block size of 2 with 1:1 allocation ratio. The random sequences for each intervention to either right or left sides was concealed in opaque envelopes and shuffled before the intervention to increase the unpredictability of the random allocation sequence. Each patient was asked to pick a sealed envelope to assign the intervention to either the right or left side. Allocation concealment was aimed to prevent selection bias and to protect the assignment sequence until allocation.
