TABLE 3.

Odds ratios and estimated probability of fecal incontinence, obstructed defecation and vaginal bulging over time among women with vaginal delivery and among women with cesarean section. Estimates are adjusted for age, body mass index in early pregnancy and educational level.

	Early pregnancy		Late pregnancy		1 year postpartum

Vaginal bulging	n = 678	n = 64	n = 622	n = 61	n = 567	n = 52
Adjusted OR (95% CI)	1.00	1.00	3.6 (1.6–8.1), P = 0.002*	1.6 (0.25–10.3), P = 0.62	8.3 (3.8–18.1), P ≤ 0.001*	1.3 (0.17–9.3), P = 0.81
Estimated probability (95% CI)	1% (0%–2%)	5% (−1%–10%)	4% (3%–6%)	7% (0%–13%)	8% (6%–10%)	6% (−1% to 12%)
