Table 4 Chi-square test of pregnancy outcome grouped by BCAA values in all embryo-transferred subjects

Pregnancy outcome	BCAA ≤ 239.10 (μM) (n = 54)	BCAA>239.10 (μM) (n = 40)	p-value
Pregnancy rate	66.67% (36/54)	45.00% (18/40)	0.036
Abortion rate	2.78% (1/36)	33.33% (6/18)	0.004

Comparisons between groups were made by Chi-square test or Fisher’s exact test for proportional data analysis.
