External validation The original developed model was applied to all patients from the external dataset to evaluate the predictive performance. The predicted probabilities for the existence of adenomyosis in this external group varied from 0.14 to 0.99 (which corresponds to 14 and 99 percent respectively) and the mean of the predicted probabilities was 0.45.
