Association analysis and distribution of chronic gastritis syndromes based on associated density

Purpose: The analysis of syndrome distribution and the association between syndrome-syndrome in chronic gastritis (CG) patients can provide references for research about Traditional Chinese Medicine (TCM) diagnosis and treatment of CG. Method: This paper applies the investigation method of clinical epidemiology, adopts probability statistics method and comes up with the concept of associated density to conduct association analysis of syndromes. Result: In the distribution of syndromes patients who have a single syndrome occupy 64.7% of the whole sample; patients who have two syndromes make up 32.2%; the situation that 3 syndromes happen at the same time has a percentage of 1.3%.spleen-stomach qi deficiency syndrome and liver qi stagnation syndrome are closely associated. Conclusion: Liver and spleen are the main disease locations of CG and these two organs are associated with and influenced each other in physiology and pathology.
