Regression coefficients (95% CI) associated with the use of NC-LPS group (NC-LPS group = 0 and AC-FET group = 1)
a. Adjusted for BMI, endometrial thickness (mm) on translate day, basal FSH level (miu/ml), blastomere or blastocyst transfer between AC-FET and NC-LPS groups
b. Adjusted for BMI, endometrial thickness (mm) on translate day, basal FSH level (miu/ml), blastomere or blastocyst transfer, singletons or multiples, the day of development of frozen embryos of the two groups
c. Adjusted for BMI, endometrial thickness (mm) on translate day, basal FSH level (miu/ml), blastomere or blastocyst transfer, the day of development of frozen embryos, singletons or multiples and the incidence of hypertension disorder of the two groups
