Association of hCG treatment with clinical outcomes in AC-FET cycles
triple-line
REGRESSION, EARLY PREGNANCY
The multivariate logistic regression models were conducted to assess the association between hCG treatment in AC-FET cycles and clinical outcomes, while adjusting for potential confounding factors. In the adjusted model 1 and adjusted model 2, hCG treatment was not a significant factor for ongoing pregnancy (model1:OR: 0.84, 95% CI: 0.48-1.47 and model2:OR: 1.01, 95% CI: 0.53-1.94), live birth (model1:OR: 0.85, 95% CI: 0.49-1.49 and model2:OR: 1.04, 95% CI: 0.54-2.00), biochemical pregnancy (model1:OR: 0.99, 95% CI: 0.52-1.86 and model2:OR: 1.12, 95% CI: 0.54-2.33), clinical pregnancy (model1:OR: 0.67, 95% CI: 0.37-1.22 and model2:OR: 0.70, 95% CI: 0.35-1.40), implantation (model1:OR: 0.61, 95% CI: 0.36-1.05 and model2:OR: 0.84, 95% CI: 0.47-1.52) and early pregnancy loss (model1:OR: 1.61, 95% CI: 0.71-3.63 and model2:OR: 1.36, 95% CI: 0.54-3.40) (Logistic regression analysis of the clinical outcomes.OR, odds ratio; CI, confidence interval.Adjusted Model I: we adjusted for women’s age at retrieval; BMI and infertile years.Adjusted Model II: we adjusted for women’s age at retrieval and embryo transfer; BMI; infertile years; bFSH; AFC; protocol in fresh cycle; number of oocytes retrieved; fertilization type; Em; triple-line endometrial pattern; type of embryo transferred; number of transferred embryos and number of good-quality embryos transferred.
