  • * Odds ratio of G3 or stage III lesions for negative versus positive TAP and HLA class I antigen phenotypes was calculated by logistic regression analysis with both TAP and HLA class I antigen phenotypes included in the models as independent variables. P corresponds to the likelihood ratio test on each variable.

  • Interaction between TAP and HLA class I antigen phenotypes was not statistically significant (P > 0.1).
