Combined acoustic radiation force impulse, aminotransferase to platelet ratio index and Forns index assessment for hepatic fibrosis grading in hepatitis B

Figure 1 Box plots show correlation between noninvasive tests and histological stages from liver biopsy. Top and bottom of boxes represent first and third quartiles, respectively. Length of box represents interquartile range within which 50% of values are located. Line through each box represents median. Error bars mark the minimum and maximum values (range). Small circles represent the outliers. Triangles represent the extreme value, which is > 3 × interquartile range. ARFI: Acoustic radiation force impulse; APRI: Aspartate transaminase to platelet ratio index.
