Table 2.

Results of logistic regression analyses for study group comparisons. The 2df test represents the genotype-wise test, and the 1df test represents the allele-wise test. CI, confidence interval, OR, odds ratio, ML, mucosal leishmaniasis, CL cutaneous leishmaniasis, NC, neighbourhood control and DTH positive, positive for leishmanin delayed-hypersensivity skin-test response.

¹Significant likelihood ratio test consistent with dominant model.

²The 2 df test was invalid, because of a zero value for GG genotype in the NC control group
