Table 2 Association test between C3 polymorphism and myocardial infarction by comparing genotype and allele frequencies of C3*S and C3*F in patients and controls

From: Polymorphism of C3 complement in association with myocardial infarction in a sample of central Tunisia

  Controls MI patients Fisher test
Number 95 170
Allelic Frequencies C3*S 0.79 0.59 Odds ratio = 0.382 p = 2.742 × 10-6
     C.I. = [0.254-0.575]  
  C3*F 0.21 0.41 Odds ratio = 2.616  
     C.I. = [1.738-3.938]  
  1. CI: confidence interval, MI: myocardial infarction.
