Figure 2: Median (interquartile range, IQR) hepatitis B virus DNA level (log10copies/ml) after antiviral therapy in due course of time. The boxes represent interquartile ranges (25^{th} to 75^{th} percentile). The horizontal lines within boxes represent the medians. The Tshaped lines that extend upwards from each box represent the highest value that is less than 1.5 times the 75^{th} percentile plus 1.5 times interquartile range. The Tshaped lines that extend downwards from each box represent the lowest value that is greater than 1.5 times the 25^{th} percentile minus 1.5 times interquartile range (DNA_B: Baseline, DNA_6: 6 months, DNA_1: 12 months, DNA_2: 24 months).
