Table 4

Maternal outcomes in TPOAb-positive and TPOAb-negative groups.

Pregnancy outcomes	TPOAb-positive ()	TPOAb-negative ()
Gestational age at delivery (weeks)	38.24 ± 1.26	38.99 ± 1.41	0.73
Mode of delivery			0.54
Vaginal	15 (57.69%)	94 (51.65%)
Cesarean	11 (42.31%)	88 (48.35%)
Placenta previa	0 (0%)	1 (0.55%)	1
Placental abruption	0 (0%)	1 (0.55%)	1
PROM	3 (11.54%)	11 (6.04%)	0.39
Polyhydramnios	4 (15.38%)	5 (2.74%)	0.02
Oligohydramnios	2 (7.69%)	22 (12.09%)	0.74
PPH	2 (7.69%)	10 (5.49%)	0.21

PROM, premature rupture of fetal membrane; PPH, postpartum haemorrhage.
Data were presented as (%) or mean ± standard deviation (SD).
The percentages of abnormal maternal outcomes between the two groups were compared by Fisher’s exact test; gestational age at delivery between the two groups was carried by -test.
