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

From: Metabolic heterogeneity of follicular amino acids in polycystic ovary syndrome is affected by obesity and related to pregnancy outcome

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