Usefulness of noninvasive transient elastography for assessment of liver fibrosis stage in chronic hepatitis C

Figure 1 Liver stiffness measurements for each fibrosis stage. Fibrosis stage 0 is offered to the control group. The top and bottom of the boxes are the 1^st and 3^rd quartiles. The length of the box thus represents the interquartile range (IQR) within which 50% of values are located. The lines through the middle of the boxes represent the median. The error bars represent the minimum and maximum values (measurement range). Significant correlation was found between stage of fibrosis and liver stiffness (P < 0.001, Kruaskal-wallis test).
