^aCanonical correlation analysis was done using the data for all of the patients and was calculated between the two sets of variables. Analysis revealed two separate significant canonical variates (first, P < 0.0001; second, P = 0.0021). Each column describes one of the two total canonical variates, with the respective coefficients for the variables in each set. IL-10, IP-10, heme, hemopexin, and creatinine were positively correlated with the second canonical variate, whereas MCP-1 and TNF-α were negatively correlated with it.
