Fig. 2

Hematocrit (packed cell volume, Ht) in the experimental and control group. It is presented as the median (solid dot or diamond), interquartile range (whiskers), and individual measurements (open dots or diamonds). Figure shows all 8 blood collections and separately the 1 st and 2nd ribavirin treatment. Asterisks (*) in the first graph indicate Ht significantly lower in the experimental group than in the control group according to the Tukey’s post-hoc test for equal groups. Black bars indicate periods of ribavirin treatment. The p-values in the 2nd and 3rd graph are from the Mann-Whitney U test without correction for multiple comparisons.
