Table 2 Spearman rank correlations between serum hormone and plasma AEA levels in women within the 1^st trimester of pregnancy.

All samples	P4			β-hCG			PAPP-A			AEA

Progesterone (P4) was measured in ng/mL, β-hCG was measured in mIU/mL, PAPP-A was measured in mg/L, AEA was measured in nM and gestation was measured in weeks. The Spearman co-efficients (r) were calculated using GraphPad Prism software and significant correlations are in bold. The number of samples (n) is given for each correlation.
