Among PLWH with and without TB, the unconditional logistic multiple regression model that compared the genotypes, alleles, carriers, or haplotype frequencies of the 11 Single Nucleotide Polymorphism (SNPs) showed an increased risk for TB onset only for individuals with the G/A genotype (ORadj=5.5; P=0.044) in the IL-1β rs1143634 polymorphism (Table 2). This evidence concerns the gene IL1B and tuberculosis.
