Multivariate logistic regression for pregnancy outcomes in the first complete ovarian stimulation cycles.

Data are presented as frequencies (percentages), crude ORs (95%CIs), or adjusted ORs (95%CIs). Adjusted confounding factors including female age, male age, total Gn dose, method of insemination, and oocytes yield.
a
P: Chi-square test for proportions between Normal weight and Overweight patients.
b
P: Chi-square test for proportions between Overweight and Obese patients.
c
P: Chi-square test for proportions between Normal weight and Obese patients.
The bold values indicated lower odds of cumulative live birth and higher odds of miscarriage, and the difference was significant.
