Figure 4From: Toll-like receptor 2 gene polymorphisms, pulmonary tuberculosis, and natural killer cell counts Homozygous TLR2 1350 T>C polymorphism and absolute natural killer (NK) cell counts measured at diagnosis. TB patients carrying homozygous rare alleles for TLR2 1350 CC genotype had higher blood absolute NK cell counts compared with those carrying common allele (p = 0.004). The box plots show 25th, 50th, and 75th percentiles, maximal, minimal, outliers (○).Back to article page
