Firstly, absolute frequency, cumulative frequency, Chi-squared test were adopted to reflect the clinical common ZHENG in three asthma stages, then the logistic regression analyses, the frequency methods were combined to distinguish the primary and secondary symptoms of the common ZHENG.
  
  
  RESULTS
  Of the 2500 questionnaires, 2428 valid questionnaires were got, with the number in acute exacerbation stage was 1273, and that 586 in chronic persistent stage, and 569 in clinical remission stage, in which the number of excess syndromes, the deficiency-excess complex syndromes and deficiency syndromes corresponding to the above three stage respectively accounted on 55.7%, 69.97%, and 76.50%. According to the distribution of each ZHENG, ten clinical common ZHENG were distinguished by criteria of the frequency percent value at least 10.0% and cumulative percent value reach to 70% or above. Then based on the OR and frequency value of each symptom, the primary symptoms were tentative identified by OR value≧3 with percent value≧50%, and that of the secondary symptoms were OR value between 1 and 3 with percent value between 25% and 50%.
