Adjusted odds ratio for mode of delivery and perinatal outcomes
| Crude OR [95 % CI] p value | Adjusted OR [95 % CI] p value | |
|---|---|---|
| Maternal characteristics and obstetric outcomes | ||
| Caesarean sectiona | 1.8 [0.9–3.4] 0.08 | 1.8 [0.9–3.7] 0.09 |
| Perinatal Outcomes | ||
| Femaleb | 1.0 [0.6–1.7] 0.98 | 1.0 [0.6–1.8] 0.99 |
| PTB (<37 weeks)b | 0.6 [0.2–2.2] 0.47 | 0.5 [0.1–1.7] 0.26 |
| LBW (<2500 g)b | 0.8 [0.3–2.2] 0.65 | 0.5 [0.2–1.7] 0.28 |
| SGAb | 0.7 [0.2–2.4] 0.58 | 0.7 [0.2–2.3] 0.53 |
| LGAc | 1.5 [0.3–7.0] 0.62 | 1.6 [0.3–7.5] 0.57 |
| Macrosomia (>4000 g)d | 1.4 [0.5–4.4] 0.54 | 1.6 [0.5–5.1] 0.41 |
| Birth defectsb | 0.4 [0.1–3.2] 0.40 | 0.5 [0.1–3.7] 0.46 |
aAdjusted OR (VAO children vs ICSI children) : maternal age (years), mother’s BMI (kg/m2), singleton/twins
bAdjusted OR (VAO children vs ICSI children): Singleton/twins, maternal age (years), mother’s BMI (kg/m2), parity (primipara or higher order)
c, dThe adjusted odds ratio does not include twins, because there were no cases of LGA and macrosomia in the twins studied in both populations studied
