Correlation between MDA, TAC, and gestational age.

	MDA		TAC		GAD
	Rho		Rho		Rho
MDA	1.000	—	−0.065	0.362	−0.191	0.007
TAC			1.000	—	0.262	0.0001
GAD					1.000	—

MDA: malondialdehyde; TAC: total antioxidant capacity; GAD: gestational age in days.
The nonparametric test Spearman’s correlation was applied. Results show significant negative correlations between MDA and GAD and significant positive correlation between TAC and GAD. MDA and TAC levels were negatively correlated, but the correlation was not statistically significant.
