Figure 2: Box and Whisker plot for the quantifi able plasma samples. The plot to the left represents the distribution of the VL from the Abbott method assay and the plot to the right represents the distribution of VL from the Roche assay. The boxes present the distribution of the middle 50% of the data (median value) and the remaining 50% are represented by the upper and lower whiskers (vertical lines). The solid line in the box indicates the median value and the ends of the whiskers indicate the minimum and maximum values. |
