highly significantp = 8.7×10 −7
The correlation between the percentages of CD27 low IFN-γ + cells and the form of lung pathology was highly significant (r = 0.63, p = 8.7×10 −7 ), but it was likely secondary to lung destruction: it appeared only when higher scores were assigned to more destructive TB forms (i.e., tuberculoma – score 1; TB infiltrate – score 2; cavitary TB – score 3; caseous pneumonia – score 4); within a group of patients with the same form of lung TB pathology (e.g., TB infiltrate) the percentages of CD27 low IFN-γ + cells correlated with lung destruction (r = 0.45, p<0.01).
