The clinical criteria for both diagnosis and efficacy evaluation of disease are also needed. To include all symptoms, tongue manifestations and pulse presentations into case report form, and to compare the differences in these clinical parameters between effective and noneffective cases by multivariate analysis may be helpful to find more specific indications for therapeutic protocol of TCM. Furthermore, It is suggested that two or more clinical trials on one therapeutic protocol are needed to identify its accurate indications.
