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 |
|---|---|---|---|---|---|
| Group 1 | Interactive Two-way SMS Dialogue | Participants will receive automated SMS messages with prompts to reply. They will have the ability to both respond to and initiate SMS dialogue. Trained Study Nurses will monitor and respond to participant messages.~Interactive two-way SMS dialogue: We will utilize Mobile WACh, a human-computer hybrid system that enables seamless two-way SMS communication and patient tracking, to provide consistent support to women and their infants during the peripartum period and 6 weeks into the baby's life. Women will receive automated theoretically grounded SMS messages targeting the appropriate peripartum period and will have the capability to respond and spontaneously message a nurse based at the clinic. During pregnancy, automated SMS will be delivered weekly. Two weeks prior to the participant's estimated due date (EDD), daily messaging will begin, and will continue for two weeks after delivery is ascertained. Thereafter, SMS will be delivered every other day for the remaining four weeks. Women who experience pregnancy or infant loss will be enrolled into an infant loss track where they will receive messages of support. | 38 | 2,467 | OG000 |
