Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

GroupTitleDescriptionWith the outcomeAnalysedClinicalTrials.gov codeSource
Group 1Open 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

Group 2Masked GroupThe 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.405,576OG001ClinicalTrials.gov
