Fig. 2From: Effects of prolonged direct hemoperfusion using a polymyxin B immobilized fiber cartridge on interleukin-6 concentration in patients with septic shock: a prospective exploratory trialTime 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.
