  1. Figures are the mean AUC for the natural logarithm of each marker plotted against time from 6 to 24 hours. Both ‘raw’ (actual values) and baseline-adjusted (subtracting the rectangular area defined by the height of the baseline reading across the 18-hour period) are presented. The mean difference (95% CI) and associated P value are given for the adjusted values. AUC, area under the curve; CRP, C-reactive protein; CSF, cerebrospinal fluid; IL, interleukin; IL-1Ra, interleukin-1 receptor antagonist; MCP-1, monocyte chemoattractant protein-1.
