Figure 1.

Median fluorescence intensity of monocyte HLA-DR expression in control paediatric outpatients, cases in paediatric intensive care unit because of single or multiple organ system failure, paediatric patients receiving outpatient follow up after multiple system failure, and healthy adults. Individual values and means with 95% confidence intervals (bars) are shown for each group (*P<0.05, analysis of variance v control groups). HLA-DR expression was also significantly lower in children with multiple organ system failure than those with single system failure (**P<0.05)
