Results
A total of 970 women were randomised; two women in the CTG+STan arm
withdrew after randomisation, and one in this arm was mistakenly
randomised before consent was obtained. Thus 967 women, 482 randomised
to CTG+STan and 485 women randomised to CTG alone were included in the
trial. Costs were calculated for 956 of these women (98.9%); the final
6 women in the STan arm and the final 5 women in the CTG alone arm were
not included as their costing data was not available at the time of
analysis. The two arms were similar in baseline characteristics with
mean maternal age of 31 years, mean maternal gestation at randomisation
of 39 weeks and cervical dilation at randomisation of 3 cm
(Supplementary Table 1).
