Time points of serum interleukin-6 concentrations over 12 h. The two groups were compared using a two-way repeated measurements analysis of variance. Interleukin-6 concentration was transformed into the natural logarithm before it was included in the analysis. For both groups, a paired t test was performed between 0 h and each additional time point. *P < 0.05. PMX-DHP, direct hemoperfusion therapy with polymyxin B immobilized fiber cartridge
