[Study of traditional Chinese medicine syndrome factors of dysfunctional uterine bleeding based on cluster analysis and factor analysis].
OBJECTIVE
To explore the characteristics and rules of traditional Chinese medicine (TCM) syndrome of dysfunctional uterine bleeding (DUB).


METHODS
Based on the collection tables of patient information TCM syndrome of DUB Epidata database was set up, SPSS 13.0 was used, information collected by means of four diagnostic methods from 1 000 DUB patients was analyzed in order to judge the DUB symptom group and analyze the syndrome factors.
