  • —, variables not included in the final model.

  • a All cases separated in the first 2 hours were due to risk factor–based EOS evaluation.

  • b Prepregnancy BMI data were missing in 12 subjects of the early initiation group.

  • c These variables were included due to their association with the main predictor (ie, separation).
