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 | • Fetal STAN monitor electrode inserted and data available to caregivers~fetal STAN monitor: The STAN monitor is a system for fetal surveillance that displays the FHR, the uterine activity and information resulting from the analysis of the ST segment of the fetal ECG. | 80 | 5,532 | OG000 | ClinicalTrials.gov |
| Group 2 | Masked Group | •Fetal STAN monitor electrode inserted, but data masked to the caregivers~fetal STAN monitor: The STAN monitor is a system for fetal surveillance that displays the FHR, the uterine activity and information resulting from the analysis of the ST segment of the fetal ECG. | 74 | 5,576 | OG001 | ClinicalTrials.gov |
