Statistical analyses of the tetramer-bound CD14⁺ monocytes detected in PBL samples from active PTB inpatients.

<p>The percentage of tetramer-bound CD14⁺ monocytes was detected by flow cytometry. (A) The clustered bar graph shows that the median percentages of tetramer-bound CD14⁺ monocytes in the PBL samples from PTB inpatients (second bar; 0.6% and 0.45%) were significantly higher than those of the control groups (Mann-Whitney U test, <i>p</i><0.01). N1 and N2 indicate the number of samples stained with the eu- and hu-tetramer in each group, respectively. (B) The scatter graphs show that a high percentage of tetramer-bound CD14⁺ monocytes was only observed in PBL samples from PTB inpatients following staining with both tetramers.
