title: Chinese literature associated with diagnosis of Helicobacter pylori.
abstract: OBJECTIVE
  To synthetically analyze and probe into the diagnosis of H pylori infection, we followed the principles of evidence-based medicine.
  
  
  METHODS
  A total of 22 papers of prevalence survey and case-control studies were selected for studying about diadynamic methods. Using meta-analysis, we analyzed the different diadynamic methods of H pylori in China.
  
  
  RESULTS
  Through meta-analysis, among the five diadynamic methods, the accuracy of polymerase chain reaction (PCR) was the highest (98.47%) and PCR was the most sensitive method (Sp: 99.03%).
  
  
  CONCLUSIONS
  Among the five diadynamic methods, the accuracy of PCR is the highest and PCR is the most sensitive method to diagnose the infection of H pylori.
