Outcome Measures
Primary Outcomes (1)
Difference in incidence of Obstructive Sleep Apnea (OSA)
The difference in incidence of OSA during the third trimester and postpartum. We assumed an incidence of 25% during the third trimester, reducing to 6% postpartum. Comparison will be made with McNemar's test on proportions at an α level of 0.05.
6-8 weeks postpartum
