5. The intrauterine device (IUD), a safe, highly effective, long-acting contraceptive method has been used routinely in women who have previously given birth but has been used less extensively in nulligravidas (women who have not yet given birth). Researchers hypothesized that the use of misoprostol would ease the pain of IUD insertion in nulligravid women and tested this hypothesis in a randomized trial (Scavuzzi, 2013). In the study, moderate/severe pain with IUD insertion was reported by 32/86 women receiving misoprostol and 62/93 women receiving placebo. Calculate the relative risk of pain among women receiving misoprostol compared with women receiving placebo and interpret this in a single sentence
