Sequential viral loads in the 50 patients identified during the serological window phase (group G, n = 11, excluded).

<p>To meet the variability in time lags between last anti- HCV negative to first anti-HCV positive, we compared the median viral load at increasingly shorter lag phases between the first two samples (T). (Panel A. T = 182 days, n = 47, p<0.001; panel B. T = 152 days, n = 43, p<0.001; panel C. T = 122 days, n = 35, p<0.001; panel D. T = 92 days, n = 11, p = 0.123).
