Primary | Ongoing pregnancy rate (excluding miscarriages associated with fetal chromosomal abnormalities) | To evaluate the effectiveness of the drug in preventing miscarriages, we examined the ongoing pregnancy rate at 22 weeks and 0 days of gestation in cases excluding cases of fetal chromosome aberration miscarriages. | At 22 weeks of gestation | |
Secondary | Ongoing pregnancy rate(all patients) | To evaluate the effectiveness of the drug in preventing miscarriages, we examined the ongoing pregnancy rate at 22 weeks and 0 days of gestation in all patients. | At 22 weeks of gestation | |
Secondary | Live birth rate (excluding miscarriages associated with fetal chromosomal abnormalities) | To evaluate the effectiveness of the drug in total outcome of pregnancy, we examined the live birth rate in cases excluding cases of fetal chromosome aberration miscarriages. | At the time of birth | |
Secondary | Live birth rate(all patients) | To evaluate the effectiveness of the drug in total outcome of pregnancy, we examined the live birth rate in all patients. | At the time of birth |
