Figure 7 Correlation between the predicted and observed probabilities of the onset of motility. The 1second probability is shown in the left figure, in which the observed probability and its CI were obtained by categorising the predicted probability (<0.2%, 0.2–0.4%, 0.4–0.6%, 0.6–0.8%, >0.8%). The cumulative probability is shown in the right figure, in which the observed probability and its CI were obtained by categorising the predicted probability (<10%, 10–20%, 20–30%, 30–40%, >40%). Equalprobability lines are also shown
