  1. Note: Data are n (%). IVF, in vitro fertilization; ICSI, intracytoplasmic sperm injection. IVF group (3204 infants) consisted of 1450 cases of singleton gestation and 877 cases of twin gestation; ICSI group (419 infants) consisted of 209 cases of singleton gestation and 105 cases of twin gestation; Control group (5371 infants) consisted of 5193 cases of singleton gestation and 89 cases of twin gestation. Bonferroni corrected p-value = 0.016. aSignificantly different from control group (P < 0.016). bSignificantly different from ICSI group (P < 0.016).
