| Title | Number of Participants Who Were Treated With Uterotonics Other Than Oxytocin | ClinicalTrials.gov |
| Description | This is the number of mothers who were treated with uterotonics such as prostaglandins or methergine, but excluding oxytocin, from delivery through 48 hours after delivery. | ClinicalTrials.gov |
| Time frame | within 48 hours postpartum | ClinicalTrials.gov |
| Population | Of 5529 participants, 4 were enrolled in the study for a second pregnancy in the tranexamic acid group and out of 5471 participants, 1 was enrolled for a second pregnancy in the placebo group. Since participants were only permitted to be enrolled in the study one time, only the first pregnancy was included in the analysis. | ClinicalTrials.gov |
