Observed and predicted* percent of women experiencing vaginal delivery for women undergoing either elective induction of labor (eIOL) at 39 weeks of gestation or expectant management (EM). *The predicted probability of vaginal delivery (%) for each decile was based on the eIOL model and cut-points were as follows: decile 1, <63.1; decile 2, 63.1–71.6; decile 3, 71.7–76.9: decile 4, 77.0–80.7; decile 5, 80.8–83.7; decile 6, 83.8–85.9; decile 7, 86.0–88.3; decile 8, 88.4–91.0; decile 9, 91.1–93.3; decile 10: ≥93.4.
