Table 2 shows mode of birth, with SVB marginally increased in the high-dose arm (10/47 versus 12/47, RR 1.2, 95% CI 0.6–2.5). The dose of oxytocin given is shown in Table 3, and shows women allocated the high-dose regimen received a smaller total volume of oxytocin, within a shorter time to the maximum dose, as well as an increased total dose of oxytocin. The first stage of labour was also reduced in the high-dose arm (Table S2).
