*Natural killer cells were defined as CD3(-)/CD(16+56)(+). Values are expressed as median (IQR) absolute numbers for CD3(+)/CD4(+), CD3(+)/CD8(+), CD3(+)/CD(16+56)(+), natural killer and CD19(+) cells and as median (interquartile range) percentages for Annexin(+)/CD4(+)/PI(-), Annexin(+)/CD8(+)/PI(-) and Annexin(+)/PI(-) of isolated monocytes. VAP = ventilator-associated pneumonia.
