Figure 1. Time course of mHLA-DR expression in trauma patients, with (gray) or without (white bars) sepsis.

mHLA-DR is expressed as numbers of anti-HLA-DR antibodies bound per cell (AB/C). Results are expressed as mean ± standard deviation (t test, * p<.01). mHLA-DR expression was not different between the two groups at days 1–2, but was significantly lower in septic patients than in non-septic patients at days 3–4.
