title: [Analysis and Discussion on Calculating Likelihood Ratio of DNA Mixture].
abstract: OBJECTIVE
  To analyze and discuss four methods of calculating likelihood ratio of DNA mixture.
  
  
  METHODS
  In the case with CNAS-T0757 proficiency testing in 2013, the likelihood ratios were calculated and compared among four methods, including unrestricted combinatorial method, Clayton's method, p2 principle method, and recommendations from ISFG.
  
  
  RESULTS
  The likelihood ratios were maximum by Clayton's method and recommendations from ISFO, followed by result of the unrestricted combinational method. The minimum likelihood ratio was obtained by p2 principle.
  
  
  CONCLUSIONS
  The unrestricted combinational method could give fUrthest consideration to both information preservation and appraiser protection.
