Box plots of median liver stiffness (TE) values at baseline and follow-up in 68 patients with HIV mono-infection (p = 0.20). All data were log10-transformed. The top and bottom of each box represent the first and third quartiles respectively. The middle line represents the median. Pooled follow-up TE values are shown for the last available TE examination in each patient. Median follow-up time was 24 months (range, 9-27 months).
