Model of care and chance of spontaneous vaginal birth: a prospective, multicenter matched-pair analysis from North Rhine-Westphalia

Table 2 Non-inferiority analysis (n=391)

	n^a	Study group	Control group	Difference (%)	95%- CI	p value
Cesarean/ instrumental vaginal birth	389	67	89	5.66	(0.42 – 10.88)	0.002
Neonatal composite outcome⁺	390	17	22	1.28	(-1.86 – 4.47)	0.021
Maternal composite outcome⁺⁺	385	65	59	-1.56	(-6.69 –3.57)	0.452
Higher-order obstetric injury⁺⁺⁺	300	5	12	2.33	(-0.45 – 5.37)	0.001

⁺Umbilical cord arterial pH < 7.10 and/or 5-minute APGAR < 7 and/or unplanned transfer to specialist neonatal care
⁺⁺Adverse outcome in the third stage and/or postpartum hemorrhage
⁺⁺⁺Third or fourth degree perineal laceration or cervical laceration; CI = confidence interval.
^aNumber of pairs for non-inferiority analysis differs from total (n=391) due to missing values.
