Spearman correlation analyses correlating plasma neutrophil gelatinase-associated lipocalin (NGAL) and creatinine (Crea) with various cytokines, all measured from samples of polymicrobial infected mice 6 h (n = 20) and 24 h (n = 18) post-sepsis induction. P-values are given. IFNγ, interferon-gamma; IL, interleukin; MCP1, monocyte chemotactic protein-1; TNF, tumour necrosis factor
