Randomization
First, 58 women were included in the work. The participants were randomly assigned to control (placebo) and intervention (ASX) groups through blocked randomization. The block size was 4 and contained letters A and B (representing the intervention and control groups). Sequentially numbered sealed opaque envelopes were used to conceal the contents. To avoid bias, participants were kept apart from other researchers during randomization. Figure Summary of patient flow through the study.
