Figure 7. Box-and-whisker plot of NF-kappaB activity showing the distribution of patients according to disease severity compared with healthy controls. Systemic NF-kappaB activation occurs in acute pancreatitis (mild and severe pooled together) compared to healthy controls (P=0.004). However, there was no significant difference between those with mild and severe pancreatitis, (P=0.685). Boxes represent the interquartile range (IQR: i.e., the middle 50% between the 2nd and 3rd quartiles); whiskers represent the minimum and the maximum value in the absence of outliers or extreme values. No outliers or extreme values were detected.
