External validation of a prediction tool to estimate the risk of human immunodeficiency virus infection amongst men who have sex with men.

ABSTRACT: A human immunodeficiency virus (HIV) risk assessment tool was previously developed for predicting HIV infection among men who have sex with men (MSM), but was not externally validated. We evaluated the tool's validity for predicting HIV infection in an independent cohort.The tool was assessed using data from a retrospective cohort study of HIV-negative adult MSM who were recruited in Beijing, China between January 2009 and December 2016.High-risk behaviors occurring within 6 months before the survey were evaluated. Area under curve (AUC) of the receiver operating character curve (ROC) was used to quantify discrimination performance; calibration curve and Hosmer-Lemeshow statistic were used for calibration performance valuation; and decision curve analysis (DCA) was used to evaluate clinica
