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).
