Discrimination performance evaluation of this prediction model showed an AUC of .776. A sub-analysis was conducted to assess whether the clinical query presented to the pathologist affected model diagnostic performance. The pathologist was directly asked to assess for the presence of adenomyosis in 142/296 patients. Model diagnostic performance did not improve significantly when adenomyosis was specifically evaluated for (data not shown).
Calibration performance evaluation showed an observed to expected ratio of 1.2, and the Hosmer and Lemeshow test that did not reach statistical significance (p= .688).
