Table 2. Adjusted odds ratios and 95% confidence intervals of obstetric complications in the systemic lupus erythematosus group.

Obstetric outcomes	PTB		LBW		SGA	pPROM	GH
	<37 weeks	<34 weeks	<2500 g	<1500 g
SLE group*	8.1 (4.7–14.1)	5.2 (1.6–16.5)	6.5 (3.9–10.8)	5.4 (1.3–22.4)	2.9 (1.4–5.9)	12.1 (5.7–25.5)	1.4 (0.4–4.5)

Abbreviations: aOR: adjusted odds ratios, PTB: preterm births, LBW: low birthweight infants, SGA: small-for-gestational age infants, pPROM: preterm premature rupture of membranes, GH: gestational hypertension

* In the multivariate logistic regression analyses, the general population was used as the reference group, and the results were adjusted for maternal age, BMI before pregnancy, parity, maternal smoking status, maternal educational status, and annual household income.
