title: [Meta-analysis for relationship between apoE gene polymorphism and coronary heart disease].
abstract: OBJECTIVE
  To evaluate relationship between ApoE gene polymorphism and coronary heart disease (CHD).
  
  
  METHODS
  Meta-analysis was applied with a random-effect model for the collected data.
  
  
  RESULTS
  Difference in pooled frequencies, d, of apoE genotypes E3/2, E4/2, E3/3, E4/3 and E4/4 between case and control groups were 2.3%, -0.8%, -8.5%, 10.5% and 0.9%, respectively. Difference in pooled frequencies, d, of apoE alleles epsilon2, epsilon3 and epsilon4 were -1.5%, -4.2% and 5.8%, respectively, with a statistical significance between four groups.
  
  
  CONCLUSIONS
  apoE gene polymorphism was involved in coronary heart disease. Persons with apoE E3/3 genotype or epsilon3 allele were not susceptible to CHD, but those with apoE E4/4 genotype or epsilon4 allele had higher risk suffering from CHD than others.
