Peripheral blood cell proportions as a function of clinical status group.

<p>(A) Monocytes, (B) neutrophils and (C) lymphocytes. The data shown are the mean+SD of cell percentage. NI-CC = Non infected community control (CC with TST induration<5 mm), i-hHC = infected household contact (TST induration ≥14 mm), sHC = household contact that developed TB symptoms, IC = index TB case. Significant differences in gene expression between clinical groups are indicated.
