Clinical outcomes
PRETERM BIRTH, ECTOPIC PREGNANCY, EARLY PREGNANCY
The primary outcome, ongoing pregnancy rate in the treatment group versus the control group was 58.87% versus 61.98% (OR: 0.88, 95% CI: 0.53-1.47). No differences were found between the two groups in terms of biochemical pregnancy rate (75.81% versus 76.03%, OR: 0.99, 95% CI: 0.55-1.77), implantation rate (57.69% versus 68.61%, OR: 0.62, 95% CI: 0.39-1.01), clinical pregnancy rate (66.13% versus 73.55%, OR: 0.70, 95% CI: 0.41-1.22), early pregnancy loss rate (22.34% versus 18.48%, OR: 1.12, 95% CI: 0.82-1.56), multiple pregnancy rate (7.23% versus 6.61%, OR: 1.05, 95% CI: 0.66-1.67), live birth rate (55.65% versus 57.85%, OR: 0.91, 95% CI: 0.55-1.52) and preterm birth rate (20.29% versus 14.29%, OR: 1.22, 95% CI: 0.83-1.80) (treatment group versus control group, respectively). No ectopic pregnancy occurred in the two groups (Clinical outcomes.All multiple pregnancies in both groups were twin pregnancies.OR, odds ratio; CI, confidence interval.
