  1. Data expressed as mean ± standard deviation or number (%). Analyses by Student t test for continuous variables and Chi Square test for categorical data sets
  2. aActive labor identified when cervical dilatation ≥4 cm
  3. bRecategorization of Likert scale responses: “satisfied” includes fully satisfied or somewhat satisfied; “Not satisfied” includes neither satisfied nor dissatisfied, somewhat dissatisfied, and strongly dissatisfied
