Figure 5. Distribution of portal perfusion values between hepatic diseases. Box plots in which the boundary of the box closest to zero indicates the 25th percentile, line within the box marks the median, and the boundary of the box farthest from zero indicates the 75th percentile. Error bars below and above the boxes indicate 10th and 90th percentiles, respectively. Outliers are represented as individual dots. Graphs show box plots of portal perfusion (a), and in patients with cirrhosis (the Child-Pugh classification system) (b).
