Finally, plasma IL-8 was associated with prolonged PICU length of stay in survivors on each day measured when adjusted for age and severity of illness and was also associated with longer length of stay on days 0 (p = 0.01), 2 (p = 0.02), and 3 (p = 0.03) when sepsis diagnosis was also added to the model (data not shown). This evidence concerns the gene CXCL8 and Sepsis.
