Viral kinetics in the eight different groups (A through H) observed.

<p>Groups are defined as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097022#s2" target="_blank">Materials and Methods</a>, depending on if viremia was detectable or not and indicated by + or −. Viral loads, presented as boxplot diagrams, in different colour for each group (A = black, B = red, C = dark blue, D = brown, E = green, F = orange, G = cyan/light blue, H = magenta) show median, 25% and 75% interquartile range and outliers. For each patient group, the first time point/column represents the last anti-HCV negative sample, the second first anti-HCV positive and the third the one year follow-up. For each group A-H the number of subjects is shown. Viral loads are presented in a log₁₀ scale, and the samples that were RNA positive but below quantifiable as 149 IU/mL, to distinguish from samples where RNA was not detected, which were set one log₁₀ lower at 15 IU/mL.
