Figure 1.
Dot plot of quantified circulating log10 EBV copies per milliliter in plasma for 309 cases of BL, and 62 controls with detectable EBV. The box plots show the distribution of quantified EBV as log10 copies per milliliter, where each dot represents 1 individual. The boxes cover the IQR, and the horizontal line in the box represents the medians, the whiskers are 1.5 times the IQR, and the dots beyond the whiskers are outliers. The P value tested the hypothesis of nonequality of means of EBV values in cases of BL and controls (unpaired t test). IQR, interquartile range.
