Multivariable models for vaginal delivery, by group

Baseline characteristics	Elective induction of labor at 39 0/7-39 4/7 weeks	Expectant management
Baseline characteristics	OR (95% CI)^*	OR (95% CI)^*
Age, yrs (per 5 yr increase)	0.71 (0.64-0.79)	0.71 (0.65-0.78)
Height, m (per 0.05 m increase)	1.54 (1.42-1.68)	1.35 (1.25-1.45)
Weight at randomization (38 weeks), kg (per 10 kg increase)	0.77 (0.72-0.82)	0.80 (0.75-0.84)
Modified Bishop score at randomization (38 weeks) (per 1 score increase)	1.24 (1.16-1.32)	1.24 (1.17-1.31)

OR, odds ratio; CI, confidence interval.

All variables were significant at p<0.001.
