Figure 4 Box blot showing LS as a function of fibrosis stages F0-F4. A significant increase in LS is seen from fibrosis stage F3 onwards. The length of the box represents the interquartile range within which 50% of the values were located. The line through the middle of each box represents the median. The error bars show the minimum and maximum values (range). Numbered symbols represent out-of-range patients excluded by the box plot.
