Influence of Expert-Dependent Variability over the Performance of Noninvasive Fibrosis Assessment in Patients with Chronic Hepatitis C by Means of Texture Analysis

Figure 8

Box plot representing the estimated performance obtained when the texture analysis system is trained with datasets provided by one expert and used with ROIs established by a different expert. The top and the bottom of the boxes are the first and third quartiles, respectively. Thus, the length of the box thus represents the interquartile range within which 50% of the values were located. The line through the middle of each box represents the median.
