Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Open Group | S31 monitors in the open mode displayed ECG ST-segment information intended for use when uncertain fetal heart-rate patterns were detected. Management of the labor and delivery for women in this group was dictated by the ST-segment analysis guidelines | 4 | 5,532 | OG000 | ClinicalTrials.gov |
| Group 2 | Masked Group | The masked S31 monitors functioned as conventional electronic fetal heart-rate monitors. The care of patients in the masked group was managed at the discretion of the attending physician or midwife. | 5 | 5,576 | OG001 | ClinicalTrials.gov |
