RECRUITMENT
Between July 2017 and January 2018, 42 women were screened and 36 women were recruited and randomised (5.1 women/month); the recruitment rate was 87.8%. Despite target recruitment of 42 women, recruitment had to be capped at 36 women (the target completed sample size) due to issues related to L-citrulline/placebo stock availability and storage restrictions. This was partially mitigated by a lower than anticipated drop-out rate.
