Effect of cancer prevalence on the use of risk‐assessment cut‐off levels and the performance of mathematical models to distinguish malignant from benign adnexal masses

Two logistic regression models have been developed for the characterization of adnexal masses. The goal of this prospective analysis was to see whether these models perform differently according to the prevalence of malignancy and whether the cut‐off levels of risk assessment for malignancy by the models require modification in different centers.
