Investigation on quantitative diagnosis of stroke with Qi deficiency and blood stasis

Objective To build diagnostic model of stroke with qi deficiency and blood stasis.Methods Get the disease information by epidemiological investigation. All patients were recurited into training samples and testing samples by random. Diagnostic model was built by statistical method, and tested by training samples and testing samples. Results Three diagnostic models were built. The best model with discriminant function of qi deficiency and blood stasis has been proven to be the Bayes model. Conclusion The diagnostic model built by epidemiological investigation has the advantage of good accuracy. It will improve the accuracy of clinical syndrome differentiation.
