Biochemical features in twin pregnant women when diagnosed.

Items	IVF group (N = 51)	SC group (N = 91)	P value
TBA (μmol/l)	20.51 ± 18.68	20.03 ± 19.88	0.890
CG (μg/dl)	2296.96 ± 1845.44	2072.34 ± 2651.40	0.596
TBIL (μmol/l)	10.51 ± 7.48	10.65 ± 5.66	0.905
DBIL (μmol/l)	3.94 ± 5.75	4.07 ± 4.20	0.884
ALT (U/L)	54.55 ± 80.43	60.19 ± 92.90	0.719
AST (U/L)	51.49 ± 73.51	54.78 ± 70.20	0.796

The data were presented as mean ± SD. TBA, total biliary acid; CG, cholyglycine; TBIL, total bilirubin; DBIL, direct bilirubin; ALT, alanine aminotransferase; AST aspartate aminotransferase.

The patients had not yet received the treatment of ursodeoxycholic acid (UDCA) when these parameters were detected.
