Predicting the occurrence of venous thromboembolism: construction and verification of risk warning model.

ABSTRACT: BACKGROUND:The onset of venous thromboembolism is insidious and the prognosis is poor. In this study, we aimed to construct a VTE risk warning model and testified its clinical application value. METHODS:Preliminary construction of the VTE risk warning model was carried out according to the independent risk warning indicators of VTE screened by Logistic regression analysis. The truncated value of screening VTE was obtained and the model was evaluated. ROC curve analysis was used to compare the test of Caprini risk assessment scale and VTE risk warning model. The cut-off value of the VTE risk warning model was used to evaluate the test effectiveness of the model for VTE patients with validation data set. RESULTS:The VTE risk warning model is p = e^x / (1+ e^x), x = - 4.84
