(a) Left: model depicting the physiological roles of neutrophil and complement system. Those genes with relative higher expression in the ICU compared to the no ICU group are depicted in red (modified from KEGG) (b) One-way hierarchical clustering of neutrophil protease genes. Signal intensity data are color-coded such that the intensity of red indicates a relatively high level of expression, while the intensity of blue represents a relatively low level of expression.
